OK, I'm home from the Beach Boys now. Anyway, I think the WT-800 should be in here too, and I'll mention it later.

I gigged the Heart-Rock (HR) last Saturday night at an outdoor gig (my new band's first gig). I have to say it's a very different beast from the DB750. It certainly has gobs of power and, in that respect, is very similar to the DB750. I was playing it through my Bergantino HT322, and had plenty of stage volume and plenty more for the audience. However, I also ran the DI out (post-EQ) to the board and took advantage of the 2,800 watts available from the EAW SBX-220 subs.

The solid-state architecture of the HR is clearly evident in its tone. Words one might use to describe it might be dry, sterile, crisp, uncolored (no, not in the pejorative sense, but in a loving way). If you want to hear your bass the way it really sounds, this is the amp. Honestly, the HR was easier for me to get used to than the DB750. The HR sounds great with the EQ set flat, and it takes only a little adjustment to make noticeable changes in the tone. It has 5-band, fixed Q, fixed center EQ with well-selected frequency centers. It's plenty versatile. Compared to the Eden WT-800, this amp is even cleaner sounding and equally as "hi-fi."

If you like the warm, furry sound of a tube amp, the Heart-Rock is definitely not for you. The DB750, on the other hand, is a different story. Before I got my DB750, I had been using only Eden amps, a WT-300 and a WT-800. It took me about three gigs to get used to the change in tonal characteristics between the two brands. The Aguilar sounds fuller and perhaps louder than the WT-800, possibly due to the four tubes in the preamp section of the DB750. Ampeggers would prefer this amp by far over the Glockenklang. The tonal characteristics of the DB750 are like an SVT on steroids, or so I've heard it said. (I wouldn't know first hand. It was all I could do to bring myself to try a Mesa 400+, let alone some old Ampeg.)

Both amps sit in the mix nicely, but bring different textures to the sound. For a lot of hard rock, I'd probably go with the Aguilar. Jazz, probably the Glockenklang. Country, either one would do, depending on the sub-genre.

If you're looking for something in between, the WT-800B fits nicely in the middle. Somewhat warmer than the HR, but more well-defined and hi-fi than the Aguilar.

That is all.

I donot have Heart Rock , but I have both Glock Bass Art Head and Bass Art Classic preamp and also DB 680 Aggie pre amp.
To my ear this Bass Art series is quite warm and very clear without being sterile. Setting is easier than Aggie DB 680 pre. If I want amore pronounce tubey sound I just add Demeter tube DI before the amp , it is a clean tube sound, but mostly I donot need that , beside the Glock has a very excellent DI connection at the back. I use Glock pre with Crest Power amp , but not anymore now because I play mostly Jazz and oldies seo the 400 Watts head is more than enough. This head is sooo good for double bass too, it can deliver a very clear acoustic tone.
My friend has got a Soul Head, but I prefer Bass Art.
I attach pic of Preamp, the Head I have yet to take.

I've gigged for two month now with Glock HR and one GoliathIII cab. I used a Sadowsky MV5 as main bass. I really like the open and honest sound of the HR. And it is really really loud. But IMO the HR/goliathIII combination lacks a little bit lows and warmth. Especially when I had to turn up the volume. I guess this is part of the characteristic SWR sound, because last week I used the HR with a (borrowed) Epifani 410UL on a big stage and at high volume.....it was HEAVEN! An big open sound with a lot of lows and warmth but also a nice definition (with eq of the HR flat). This cab is gonna be mine very soon!
 
Thanks for the direct comparison... that's pretty much what I was hearing in my 'indirect' A/Bing of these two very nice pieces of gear.

I guess this again supports the idea that I forwarded in my original review of my HR... if you want the volume and headroom of the DB750, but with a cleaner, tighter, punchier, quicker sound with more tone control, the HR is a great option. It sells for about the same price as the DB750.

If you are more oriented toward big, fat, tube like tone, the DB750 seems hard to beat.

However, considering cost, size, weight, and versatility... unless you REALLY like the tonal voicing of the Glock or the DB750, the Eden800(b) or 1205 would seem to be, by far, the best bet... totally versatile, only two rack spaces, under 30 pounds, punchy and loud with just enough tube presence to be warm without going over the top on the wide bottom and tube give sort of thing. I think those big Eden's are the best thing out there for the price... you can play ANY type of gig with them... metal, funk, country, pop... they just work. If I wasn't such a boutique whore, I'd still be using them!

This is quickly becoming my favorite rig of all time!
 
Munji, No comments about the weight? I owned a DB750 and have handled Kens Heart Rock and I find some err.....let's say discrepancy in the weight stats on the two heads. The Heart Rock is listed at 40 and the 750 at 47. That is the heaviest damn 7 lbs. ever:p I found it was almost harder to lug around my 750 then my old eden 410 cab! I liked to think of the 750 as a light SVT, in that class it definitely shines. But it is by far the heaviest 47 lbs. I've ever picked up. When I shipped mine it was 78 lbs. shipping weight with an SKB Rack! Me thinks the fellows who do weight stats at Aguliar must be ex movie star publicists or accountants for the pentagon.:rolleyes:

:D I was also curious about Munji's direct weight comparison, since I too found that the DB750 felt MUCH heavier than the HR... however, never lifted them side by side.

I've moved them both around and the HR is definitely the lighter of the two.
 
I've played and owned Aguilar and Glock and to me there is no comparison. The Glock simply blows everything else out of the water. Aguilar seemed really dark to my ears. The HR can be plenty warm. It depends on the bass, cabs, and EQ. I found to really take advantage of the "Glock sound" you really do need to pair the amps with Glock cabs. I went from using my HR through a Berg HT322 to a Glock Double (2x12) and it was a night and day difference. The Glock cab was less edgy and much sweeter sounding. There's no goin back from Glock for me.
 
One more time.
I put some different tubes in my DB750. It came with Sovteks and EH tubes. Currently I just have replaced the Sovtek 12ax7wa (in V1 and V2) with Telefunken NOS Black Ribbed Plates. Sounds noticably tighter and not as 'wide/slow' on the bottom end. I've even started to engage the deep-switch which I've never engaged before changing tubes. I'm thinking even a set of JJ would help. I also tried, in the same sockets, two GE 5-Star 5751 and it tighten up the bottom, had slightly less gain. I found I like the Telefunkens better so far. Will gig test this weekend.

I don't know why Aguilar uses those Sovtek 12ax7wa, I don't much like them, however they sounded pretty good in my Demeter 201s into my IP310.

Anyway, those of you who have a DB750 and are not compeletly thrilled as is, try a different tube in your V1-V2 sockets. It's worth it.

I love the DB750 even though it is heavy and somewhat EQ limited. And true, it's not my 'end-all' sound or amp, but for a 'not that heavy' rig with tons of power and pretty good options it da bomb.

Munji's just got bigger guns than either of you two little girls :hiding:

Munji, nice comparison> I like your posts just as much for entertainment value as for informative value...

I don't think the 4 tubes in the Aguilar are all in the preamp. One is for the input, another for the EQ, one for the Deep switch, and one for the DI ... something like that, which is from memory but it's listed on TB somewhere.

My DB750, a newer model, weighs as spec'd and I don't find it an onerous carry.

They use the Sovtek tubes because no others are really available in large quantities. If they start going with NOS/vintage aftermarket tubes they'd have to increase the price even more and the sound would vary from one amp to the next.

I tried a few different tubes, but didn't get divergent enough results to bother so went back to the originals. I'm not as into chasing a tone with a lot of pricey tuibe swaps as I used to be.

I'm with you on the tube thing. Too much variability for me... too much voodoo and non-repeatable results. By non-repeatable, I mean that there seems to be as much variation within tube brands and models as across... more just 'luck' it seems.

I feel very lucky that I enjoy the sound of high quality solid state pre's and amps:hyper:
 
well,

interesting thread!

i am lucky enough to own both of them and i think it is very difficult to compare these amps. it is the same as the comparism of the lakland 55-94 with a sadowsky jazz. they are not comparable since the philosophy is different. like mercedes benz and porsche.

the heart rock gives you very much the sound of your instrument, is does not colour the sound very much (though it adds by far more sound than the bass art classic) . the db750 adds its own sound and is to my ears pure tone - and what a beautyfull tone! i love both of them and find it hard to decide every time which one to use.

one thing i would like to add:

at rehearsals i have to turn the volume of my heart rock almost at half (5 to 6 of 10), while the db750 is so incredibly loud at 2 of 10. i don´t know if the db750 really is louder. i find it a little hard sometimes to tweak in the right volume on it. the design of the volume pots seems to be different since the heart rock still gets noticeable louder between 5 and 10 where other amps already give their full power at 3 to 5 of 10.

i love them both. the heart rock seems a little more elegant to me whereas the db750 is raw power and sound pure.
