Overall Rating:
The best thing I liked about this amp and the reason I bought it was for the sound quality. It had more natural sounding guitar tones and absolutely amazing distortion sounds than other amps I have tested. I would definitly buy another Waller Amp. One important aspect to this amp was the ability to use different quitars with the high gain distortion and still hear the true sound of the instrument. For those of you who remember the Rockman, no matter what guitar you plugged in it sounded the same. This is not the case with the Waller Amp.
Price: $420.00 (new)
Where Obtained: Pontiac Music and Sound
It has a bright switch. Channel gain for clean and distortion, active bass, middle and treble. User selectable Decimator noise reduction to eliminate high gain distortion noise. Has channel switching and built in effects loop. And footswitchable gain boost in the distortion channel. Amp is all solid state but sounds just like a screaming valve amp.
Sound Quality:
I play Fender Strats and Gibson Les Paul. I play a wide variety from blues to rock to melodic and the amp does well with all styles. I have never heard an amp that had a better distortion sound. It is definetly quite because of the Decimator noise reduction which eliminates all background noise even at the maximum gain setting for the distortion setting. I can even get subtle bluesy crunch in the clean channel.
Ease of Use:
This amp is voiced incredibly well even though it isn't programmable. My favorite tone setting in the distortion setting also provides excellant and warm tone when playing clean. It is very easy to use.
It is a new amp and I haven't had it very long but it appears to be very well constructed and is 100% solid state so no need to replace tubes. I have used it for all my gigs and recording and have never had a problem with it.
