OK, here goes... My computer service glitched so I am @ the local library. Nix the PowerWerks due to small speaker size (a uke has enough treble as is), limited Euro availability, and poor off grid potential. Done. That little Vox MV50 AC puts out a true 50 watts @ 4 ohms and only has 3 control knobs, volume, tone, and gain. Your sound modeling will happen thru your very fine pre-amp pedal. Just keep the gain down and use the volume and tone controls for the basic adjustment. If you want to chase the sounds of Jimi Hendrix, Mark Knopfler, Carlos Santana, or Leslie West, crank up the gain. Plug that little Vox box into a 12' or 15" unpowered 4 ohm p.a. speaker or monitor cabinet with or without horn and you will be heard. There is also a headphone jack on the back. If you cannot find a 4 ohm cabinet just get an 8 ohm one and purchase the same later to parallel should you need more volume in a larger venue.
