I used the BH550 today in an outdoor gig through a Barefaced Super Midget. Plenty of power on tap. The EQ worked nicely to control some boominess. It was digging the tone w/ the "subtle compression + drive" toneprint. I had gain and volume at noon and it cut nicely.
I did some comparisons at home to my Teacamp Puma 500 through a mixing board to my headphones this afternoon. The voicing is actually very nice - compares well to the Puma 500 with the toneprints off. I will say, though, that it starts clipping at a much lower gain level than the Teacamp. IE the DI level is more constrained than the Puma 500 and the starting "baseline" for the volume knob is lower. Not sure if this would matter as I haven't tested the full range of EITHER volume knob in a live setting.
Other observations:
- The BH550 is HEAVY. It is nearly as heavy as the Rh450 by feel. I haven't weighed them or looked at the specs.
- The BH550 is bigger than I expected. I was thinking it would be lighter and smaller than the RH450 (at least I was hoping it would be)
- The tone controls do not have a center detente (an annoyance for me)
- The two tone prints cannot function simultaneously (a bummer)
- The tuner is UBER responsive. It locked into the B string FAST. Loved it.
- The mute switch is small and right next to the volume knob and it looks identical to the tone print switch - easy to mistake one for the other if you are moving too fast (a minor inconvenience)
- I really like the EQ points for boost and cut - lots of options here
So:
- I like the voicing
- It's heavier and bigger than I'd like
- The tone print and tuner are nice
- The EQ is very musical
So bottom line - a fantastic backup amp, a great amp to bring if you don't want to haul your pedalboard and want a quick set up, or - no reason why it can't be a good primary. For the money I think a no-brainer particularly if you can get at 10-15% off the $499 MSRP during a sale. For me, it will be my back up.
