I bought this amp as a backup for my tube amps but it became my main amp. It sounds indeed very similar to the tube amps like a Twin '65 that I owned some years ago. The behaviour is different though than a tube amp: whereas a tube amp may break up after a while with the same volume, which gives the tube amp its own flavor, the BJF keeps the same sound as initially set-up all the way. This is exactly what I was seeking: I am more into clean or slightly overdriven but "controllable" sound, whatever the volume is.
The headroom is huge. With low output pickups, you hardly bring the amp to distortion even on the high gain channel... like on a blackface! For that purpose, you need to add a pedal. Sounds huge and gives the same tone with my Eminence Ramrod 10" speaker as well as with my Mesa Rectoverb 12" cabinet.
The reverb sounds good to me. On the other hand, the tremolo sounds too much like a square signal and not sinusoidal enough to my ears. I solve that by adding my own analog tremolo.
Overall it does impressively sound like a 60's blackface without the drawbacks associated with the tube maintenance.
The absence of tube make it a smaller amp. I would have appreciated to additionally have a fitting bag to carry the set with its power supply.
The box, actually a silver-face :), is all metal and looks solid built.

- great blackface tones with the controllability of a solid-state amp
- small
- connectivity (convenience of an effect loop, preamp out beside speaker out, footswitch ports)
- good reverb
- same tone/behaviour with different cabinets

- square-signal tremolo

wäre ein sehr praktischer amp
der sound ist toll, wenn auch etwas sehr "processed"

aber das problem ist, dass er rauscht.
angeschlossen an 8 ohm ... gain 5, master 3 im rhy clean kanal ... und es rauscht wie mit einem overdrive stomper

evtl liegt es daran, dass alles nur strom aus einem netzteil wie für einen pc monitor bekommt. bin kein fachmann aber gibts im amp selbst dann keine erdung ...? evtl deshalb das rauschen. quilter 101 im selben setup rauscht kaum, aber der klingt einfach schlechter.
