I've been a happy RH (450 then 750) user since 2009; happiest over the past year, after really having gotten the semi-parametric mid/shelving point setup truly under control (vs being somewhat hit-or-miss). Since deciding to keep a backup head, I've been on something of a quest to try everything I can. I figure at some point, a head may knock the RH750 out of the top slot and I'll have a go-to amp that I'm even happier with.

My latest buy/try/backup amp is the TCE BH550. I wanted to give some personal initial impressions and comparisons to the RH750, but wanted to hold off until I played in a group setting, which I did last night.

Unboxing -

Totally a minor point, but I'm always impressed with TCE's packaging. It's done very well with great protection and attractive/convenient touches, like a strap handle on the box. Anyway, on pulling it out of the box, it was bigger and heavier than I expected. I find that I can read specs and see pictures but still form a mental image that doesn't quite match the reality. My mental image here was that it would be a little smaller and lighter. In hand, it seems about the same size and weight as the RH750. That's not a bad thing. I'm not really a fan of the appearance (I guess it's the color and the two white knobs - I like the lines, fit and finish), but it feels compact and substantial with nothing striking me as flimsy or cheap feeling; it seems the "right" weight for its size (where the BX500, for example, seems overly light for its size and the case seems to lack some amount of substance). Where I might prefer buttons, the switches used are small and kept short with a longish throw, so they're nicely functional yet sturdy feeling.

Initial A/Bing -

I went back and forth on my Schroeder 212PL. The RH has the advantage of already being setup to my liking. I made these first comparisons without using any of the comp or tube TonePrints. Set flat, the BH is pleasant enough if just a bit "dry" with more hi mid than I liked. Pulling the contour switch on my bass sounded great, actually very balanced. I basically could have left it at that, but for general use that seems to bump the bass a bit much. I made some smallish adjustments to the EQ (nothing more than 10:00 or 2:00) and found a sound that compared nicely to the RH in an overall way but was clearly different. I've usually been able to at least find some kind of words to describe differences I'm hearing, but this one is leaving me at a bit of a loss. I don't want to make too much of it because it's slight and only apparent as a direct comparison. But the word that keeps coming to me is "dry"..."harshness" and "brittleness" are too strong of description, but are in the realm of what I mean in a very slight way; as an undertone..."unrefined" "lacking density" maybe? The best I can do to try to convey is that the quality I'm hearing seems to be in the base character of the midrange frequencies, not the level. With an otherwise balanced tone, the "dry" character is there, but efforts to drop the dry quality end up with the frequency noticeably muted/muffled…no idea if that makes sense, sorry. In direct comparison, I found the RH preferable; richer, smoother, clearer (as a relative matter, less of those qualities = "dry").

On some of the features -

I'm familiar with the BH's tuner from owning a BG250. Making a more direct comparison to the RH, you can say that the BH tuner certainly works…works well, but the RH tuner is way ahead.

The RH's presets are one of the things that seem "nice" and probably become under appreciated when you get used to having them. Even just for saving a single setting. Using other amps, reminds how easy it is to accidentally bump knobs and sliders…you do that, even just a little bit, and what you had is gone. In comparing to other amps, I've found this to be a real usability bonus that the RH has.

As with the tuner, I'm familiar with TonePrints. I never really found much use for them. I'm not an effects guy, and the little use I have for them, I get from my B3. I also don't like overdriven tone as a staple sound. Trying out some of the tube and compressor TonePrints is a next thing on my list. I'll be interested to see if one of the options works to wet that dry character that I'm hearing.

With a band -

I had a rehearsal last night and switched back and forth between amps every few songs. The BH did fine, but I found myself continuing to prefer the RH. The same characteristics showed through with guitars and drums added in. This also needs to be re-tried with a TonePrint on the BH…we'll see.


The BH is "good" and completely useable. In the absence of a direct comparison, I'm sure it would be golden. Bottom line, so far, is that I personally like the RH better...others' MMV. I tend to bounce back and forth some in my thinking on the value of simplicity in EQ versus the power of highly controllable (if more complex) EQ. Given the limited circumstances so far, simplicity just isn't getting it. It's entirely possible this could be a matter of the BH just not being as good a match with the Schroeder, and without para-EQ, the BH can't be made to match up as well.

I'll be doing a little "shootout" with a friend. We'll get an RH450, RH750, BH550, TH500 and LMIII (which, from what I've seen on TB, gets a lot of love from Schroeder owners) together with the 212PL and a Berg CN212.

Sounds like you didn't need to, or get a chance to open them up... but did you have any feel for overall volume capability of the 550 vs the 750?

Yeah, it's a no need/no real interest kind of thing. Both are more than loud enough for me.

As far as getting "a feel" goes, most really, how could I? I think while we intellectually know that you can't necessarily tell anything from knob position, there's still a temptation to try to glean something from it. That'd be the only thing I could give you.

Still, my sense is that they're probably in the same ballpark and any difference in either direction isn't meaningful...that is to say, between these two amps, I don't believe you're going to find anyone saying, "Well I got one and it wasn't loud enough for me, so I got the other and now it's cool."

So, I got a chance to spend some time doing comparisons yesterday.

Heads - BH550, RH450, RH750, Tonehammer 500, and Little Mark
Cabinets - Bergantino CN212, Schroeder 212PL and we threw in the Ampeg 410 into the mix a couple of times just because.

My friend's interest was in comparing his RH450 to the RH750…contemplating an upgrade. My interests were in hearing the BH550 with the CN212 and hearing the TH500 and LM with my 212PL.

On the differences between the BH550 and RH750 I had noted on the 212PL, while I did find the BH550 played well with the CN212 (possibly a better match than the 212PL? Maybe), I still found the tone of the RH750 slightly preferable, again, a bit more "rich" and "refined" sounding, whether comparing on the CN212 or 212PL.

Old news, but the RH750 is a good bit louder than the RH450, so that's a yawner. There was a suggestion that Tweetertone might make the CN212 sing a bit more. There was a noticeable difference, but hardly night and day. Far more subtle than I would have thought.

The Markbass, which my friend hadn't been using in a while, sounded great through both cabinets. It looks like he might bring that back into some regular use. I was really pleased with the sound through my 212PL. I liked the TH500 with the 212PL but preferred what the LM was doing with it…lacking nothing.

My friend's overall conclusions kept coming back to the fact that he's happy with the sound and volume of the RH450. Eliminating the loudness difference leaves only the difference that Tweetertone makes, and that wasn't compelling enough to move from the RH450 to the RH750.

He liked and was intrigued with the BH550. There was a momentary GAS twinkle, but again, even with an attractive price, there's nothing compelling enough to make a move away from something that he already has that's getting the job done.

A big takeaway for both of us was that any of these combinations would be "good" and meet our purposes; with some EQing, all could be brought into ranges that met with preferences. You can compare and find differences very easily, but differences that make a real difference are a bit harder to identify. From that prospective, the BH550 stands up well in this group of amps. In some respects and aspects of direct comparison, it stands a little bit ahead and in some areas, it wouldn't be my first choice.

I liked the Markbass with the 212PL enough that it's going to be my next move, probably sooner than later.

I have a BH500 and I find that it is a little stale or dry as you stated. That is exactly how I describe the sound. Not appealing sounding solo but does well in a band mix. Lacking density and richness but gets good and loud. The tone reminds me of the old Crate Thunderbass heads. Not bad, not great.

I prefer my Walkabout and Eden WT300 but for a backup amp I'm not displeased. Especially because it was fairly inexpensive.

It's difficult to make these "critical" points with the proper weight given to the comparison. As observations, most of what I said was only in direct comparison to something I'm used to and already like very much. Without listening to them seconds apart, I'm sure I wouldn't have heard those aspects. I also had to stretch to define and label the differences I was hearing. The differences are not at all stark. The BH550 sounds very good to me (just not as good as the RH750...and that's by a small margin).

I've never heard the BH500, so I can't say for sure, but since it uses APM (which has the goal of "vintage" sound by emulating response of tubes) and the BH550 doesn't, I'd expect them to have a slightly different base character.

I'd love to try a Mesa and an Eden with my Schroeder cabinet. The Markbass definitely struck me in a GAS inducing way.
 
Small update -

Recalling how I found that amp sims through the BG250 did some pretty magical things as a "sweetener," I decided to try that out with the BH550...and BINGO!

I had tried it with the RH750 and BX500, and I can't say that it really brought anything special to the table with either of those heads. That had me kind of wondering if the combination wasn't doing things I liked with the BG's cabinet more than the amp section.

I set the BH550 EQ at noon and ran through the Eden, Markbass and SVT sims (cabinet mix on 0). All were fantastic. Both the Eden and Markbass "fatten" the sound up making it richer, rounder and more lush in a way that the amp's EQ or my bass's EQ just doesn't exactly get to. It seemed the exact thing that was missing in comparison to the RH750's sound. The SVT sweetened it up to that perfect rock tone. The grit is understated but present...like a perfect grind and gank edge for throwing on a Who tune.
