UL 502 vs. TF 550

Just before I bought my 410ul from my good buddy Scott Pazera (Epi Dealer, great deal btw) he let me try a UL112 and his personal 502. I directly a/b'd with my TF550 through my NV215, HT112, and UL112. I used my Sadowsky basses PJ4 w/flats and JJ4 with bright nickels. The 502 sounded very good and as most say here is more hifii. I found the TF to be more clear actually....

Anyway the thing that suprised me was the 502 made all the cabs start to fart and break up when ever I turned up my bass eq on either of my Sads. With simialr setting on amps and bass I went back and fourth to all the cabs and the 502 made them break up ... sounded bad to me. The TF did not at all react this way. Trying to compensate, I couldn't get a good tone or volume on 502 ... strange.

I hope to try it again soon with my 410UL.
Maybe I just don't know how to work the 502 but it seems straight forward.
 
I noticed the same breaking up/distortion from my 502 going through a UL 2x12....
My Walter Woods never ever breaks up....
Could it just be that the UL cabs want more power then the 502 puts out? I even lowered the output trim on my bass and try to keep the gain down but if I really dig in she farts out?For the most part when playing finger style..
If I keep a light touch she is fine and she is also fine when I slap even if I slap and pop really hard...Just doent make sense that digging in finger style makes her distort..
 
Hmmm. I've gigged my Epi PS600 (similar to the 502) with my UL212 and have never experienced any farting. I've used my Sadowsky RV4 and my NYC Standard 5 with no problems. I play in a LOUD classic rock/blues band with no PA support.

Same, and I've owned several 502's and a PS600. Always crystal clear! That's odd. . . :confused:
 
Yes I agree this is odd, kinda relieved I'm not the only one that noticed this. In my expereince gear from the same manufacturerer always seems to work the best at least match wise not always tone wise though. Anyway I'm sure we can collectively figure this out.

Hmmm. What is the power rating and resistance (ohms) on your speakers?

I have the PS 600 and the PS 410 cab. I used it at a rehearsal with drums, keyboards, and guitar and I didn't experience anything like that. The tone was even and clean all the way through.

hmm...

could be the gain settings, which is the key to making the epifani sounding good. from what i could tell when i owned the TFB, however, that was a very hard amp to push into unwanted overdriven territory. even w/ the gain set rather high, stayed pretty clean. but again, w/ the epifani amp, when the red comes into play, time to back it off a bit. was especially apparent w/ my sadowsky rockin' preamp.
 
This Sunday was geartastic. Apparently, after me not seeing Henry for only a short while, he has decided to arm a small brigade of bassists in the near future. His collection was as follows, with small reviews.

Bongo 5: Not my thing in the end, but tonally unique from anything
else I've tried to this date.

Stingray 5: Still a classic, and a class act as well. Awesome B
string that is still current with today's taste for
"modern piano tone"
Sting Pbass: You just can't keep a good P down. Period.

Headless Washburn with Graphite neck:"Holy Zingy ToneBatman!"
Pick style Nu-wave tone? One of the best takes on it.

My RV5 with single coils: complete crapstick. Don't waste your
money on a Sadowsky, in fact, don't even look at
their "in stock" page on the website. Instead I will
monitor said page with credit card in fist.:D

The Thunderfunk suprised me on some accounts, and confirmed some suspicions that I had speculated upon in the last week, namely that the TFB550B might just B a better option for 'my sound'. In comparison, I noticed some things that I didn't
like about the UL502.

First off, let me give some props to Henry for graciously allowing some of his freetime, and for disengaging some of my teeth from my gums via his two Bergantino 115's. Man!!!! That sound's gonna stay in my head for some time! Literally. The sonic thrust of the low B of my Sadowsky made a dent in my skull. Awesome cabs.

I started off on my UL502 thru the UL410 just to get some reference. Don't count it out. Its deep sounding with plush lows (almost tube-like on the bstring), and the high end is sweet and airy. I messed around on it, gathering thoughts on what I initially was missing from it. I liked the Bass knob in that it gave me huge presence down low, but yet that thickness didn't exactly translate all across the fingerboard, which IMO left a slight lack of punch and girth from the A-string on up. Very subtle, and something I didn't necessarily notice in the first week or so of gigging.

*****At this point I should stop and point out that everything that I noticed as 'lacking' in the UL502 only appeared to me in comparison to the inherent sound of the Thunderfunk. I simply want to evaluate what differences I heard in every comparable frequency range, ie. Lows Mids and Highs.*****


So, getting back to the lows, while the lowend on the UL502 was actually the first thing I loved about it in that it had a 'spread' to it that reminded me of tubes. Well, the Thunderfunk has more than a few options for getting a thick lowend that also extends into the midrange (we'll get to the midrange in a sec). First, when placed flat, a simple click to the left on the Timbre knob makes a dramatic difference. The amp goes immediately from solid state punch, ala GK IMO, to thick and round like a tube amp. Amazing little knob, and as many have said, 'worth the price of admission alone'. If your not satisfied at that, you can still dial in even more extended lows via the Bass knob or the parametric mid range that allows you to get surgical in those 'big booty frequencies', or 30-120 hrz. And the sound remained a lot tighter than the Epi did, which is important considering the 'thick to outrageous' bass knob on my Sadowsky.

While the lowend department is a toss up between the two amps, expecially depending on the nature of your B string, the midrange was simply 'No contest' IMO. The Parametric EQ on the Epifani is definitely useful, and I could basically get slight variations on the same thing. That "Epifani Tone' was never far away on any setting. I really, REALLY wanted the Para-mid knob to extend down into the 100-120 hz region. But then again, I like a darker sound with a lot of low mids. To me, the mid knob on the UL502 was adequate compared to the surgical precision of the Tfunk. There's almost infinite options, if you even need them that is, because the flat tone is just about perfect in itself. Set flat, the Thunderfunk is punchy and quick, and would cut through anything. After that, its up to you to get any conceivable sound you might want, be this thick and fat, punchy and bright, deep and wide and modern, vintage roundness, basically whatever. For this reason, I personally will be making the switch.

The Epifani is a great amp nonetheless. It has a definite sound to it. A unique stamp if you will. It takes the tradition of 'clean and crisp with deep bottom' that was introduced in with amps like SWR's and completely updates it. In fact, I will venture to say that the UL502 reminds me a lot of early SWR amps. Maybe thats why longtime SWR proponents such as Andrew Gouche and Joel Smith made the switch? Perhaps. At first, I thought that this sound would complement the darker sound of my RV5, and that I'd be set up. I was simply wrong. No harm done though, and if I was strictly a 'modern tone' proponent (fat lows with crispy top end) or even a more 'modern' player (fast chops, double thumping high octane slap runs, ultra techinical busy lines), than this would totally be my amp. That being said, for the limited slapping that I do, the Thunderfunk delivers, and actually has more crispness to the high end whereas the Epifani's high end is more 'airy'. Different flavors in that regard.

Its just about the best for that tradition of players such as Matt Garrison, Tony Grey, or any player that plays a gig that demands equal time spent soloing and grooving. Now, this is not to say that the Tfunk is NOT for these players, because even in that regard, the tfunk can somewhat approach what the Epifani is doing. Its just that, for my needs, the UL502 can't come close to the warm vintage-vibe that the Tfunk can put out. I just couldn't find it in there, and God knows that I tried everywhich way. The Tfunk can do that with one click of the timbre knob.

As I write this, it reminds me of my decision to let go of my DB750. In fact the UL502 has a lot in common with Big Daddy Aggie in one simple regard: they both have a unique tonal stamp that you'll either fall in love with or later fall out of love with. I'll always miss the corpulent power of the DB750. And in the same vein, the UL502 has its own 'identity' that can't be duplicated exactly. Its just that everything I loved about the UL502 in the first place can be had on the Thunderfunk as well. So I'm really not giving up anything.
I was craving a more hi-fi sound than my DB750 could give me. The UL502 delivered marvelously on this account. But I completely lost out on that tube-like thickness that I loved about the Aguilar. In a sense, the Thunderfunk is an exact marriage of tube-like warmth and hi-fi sheen. I think that in the end this decides it for me more than anything else. Now if Dave Boonshoft and crew would only give me that DB750 thickness in a 20lb package, then I'd be writing a whole other thread. :D

Until that day, I know what I'm goin with. Anybody want a UL502?
 
nice little comparison, elmon!

the "tube like low end" w/ the 502 is spot on, and yea, i like how the TFB does thicken the lower midrange. and while i'm not gonna discount your ears, cause its what you're experiencing, to my ears, the 502's that much clearer and hifi to me. but again, seems like the TFB is a waaay better fit for your needs/ears/booty. :D

but not to throw another curveball your way, have you tried an aguilar ag500? IMHO, the low mids knob, bass knob, and deep switch does spine tingling things for adding some fattening lower midrange lower end thickness to an epifani cab. dare i say, almost like a close cousin to the TFB sound. ;) one of my fav sounds, and actually kinda makes me regret selling my ag500.
 
nice review of today's happenings ElMon.. and as always, it was a blast hangin out wit ya.

What's cool is, that even though we are completely different players. (you have skill, I don't!!) and we play different styles of music.. we both seem to like the same thing as far as tone is concerned.

I was stoked to hear that UL502.. I'd been wanting to try one out for a long time. I really thought I was going to fall in love with it when you brought it over. But I didn't. It's a great amp, don't get me wrong. But now I know how much I like the T-Funk. Especially the "timbre" and "enhance" knobs. I could almost live with just those two knobs.. and no eq section.. (I said ALMOST!!). It just seems that for me... the T-Funk comes by my tone naturally, and the UL502 had to be tweaked to get it.. it could get there.. but you had to fidget with it.

The UL502 cam closer to what I would want, when paired with the Berg HT115's, than with the UL410 you brought. But the Tfunk just nails what I'm looking for.

Anyway back to the thread topic.. the 502 didn't seem to reproduce all the dynamics as well as the T-funk did. It seemed to do well with the lows, and the highs.. but it almost seemed to have a mid scoop. It could also be the room we were playing in.. with the odd layout, the old wood floor underneath some crappy carpet.. etc. Maybe the room eats the mids... but the T-funk didn't seem scooped to me. There wasn't a mid hump either.. it just seemed to offer the full spectrum of each note better.

I could see why a lot of people would prefer the 502 over the TF... but for my needs.. the TF is a better fit for me.
 
I've never tried a UL502, but I've owned a couple DB750s and AG500s and T-Funks. The T-Funks just do it for me. The DBs are gone, the AGs are gone and MANY others have passed through my hands and the T-Funk is still here along with a nice A.M.P. SL-1 pre-amp and Crown rig (esstially a 1400 watts T-Funk). I'm lovin it!!!!!!;)

Man, that really makes me want to go and by a CA9 or macrotech or something :)
