Yamaha BBT500-115

Amp 500w @ @ 3ohm 2ohms 375 250 @ 4ohms transistor
outputs 1xlr out, in 1jack 1jack out, 2jacks speakers, in 1midi 1midi out, effects loop.
digital preamp, parametric EQ 5-band compressor fully adjustable 11simulateurs amp, 5presets.
preamp with all possible settings, Store 5presets. I play bass 5 string fretted / fretless and double bass, the function presets, this is what I needed.
handling of the amp quickly if knows about the parameters and parametric equalization
compression. The amp simulations are nice, I use mainly vintage.
Amp attack with preamp (if I use a pest station SansAmp in bypass mode and boost and more problems) I took the compact 10pouces.

UTILIZATION

Very simple configuration, but given the range of parameters, it can take more time for a novice. However, all parameters are well explained in the manual. we obtain
the sound is desired, effective bluffing!

SOUNDS

I play mostly jazz and some soul / funk / fusion.preset its fat to Meshell for fretted, the preset medium fat for the Jaco fretless, preset and clear forthe serious bass, a supercharged preset for slap preset and mute. I love the simulator vintage, but the others are very good too, matter of taste.
very good potato as sufficient to repeat with a drummer, I live for connecting a speaker 8ohm 15pouces and, boom! it pete, power very comfortable (I remember I 10pouces @ 4ohms version, plus a 15pouces @ 8ohms = 3ohm therefore delivers the amp 375watts).

OVERALL OPINION

I've had about a month, I did two concerts and a few repeats or I literally bluffed my colleagues. I was looking for a small amp powerful and comprehensive for all situations, I think I have found, for the moment I have not reached its limits, I only with coffee.
