Tweed!!

Fantastic emulator. Love the tones…would love to see a “whizzer” released for this. 4 preset buttons, maybe some reverb presets for the “reverb kill” and of course, a Peterson Strobe built in to the “tuning mute.” Just a thought…

Awesome

I really love to play Blues and also i love Grunge and Lofi, this Little device is shifting me closer to my dream sounds than my tube amp could!

Thx Universal Audio for this awesome broken sound, creamy warm cleans and thick Gains, everything in between is possible and sounds awesome.

I just would appreciate to switch via footswitches between my favorite presets to be able to jump through while im playing, instead of taking my hands away from my Guitar just to switch them through UAFX App.

And lastly using the boost footswitch mode while im using 4 cable method would also be nice, cause sometimes i have no need to Bypass the woodrow cause it’s awesome :)!
