Wait you’re after an amp to use for bass electric guitar and bass?
The new 2015 Ashdown B Social sounds perfect.
Otherwise I’d have to recommend the Orange Thunderverb 50 or the 200. Which obviously you’re looking above you’re budget, I however will say it’s worth paying the extra, if you buy a cheap amp that’s made for bass and play guitar through it, you could fuck it. If you buy an amp made for guitar and play bass through it, you will UNDOUBTABLY blow the amp.
I’d recommend you Pay the extra and get the Thunderverb Head and get a cheap cab. The Thunderverb is designed for both guitar and bass, perfect for studio work etc etc.
The Ashdown B Social has only just been released and I’m not sure if prices have actually been announced yet. But look into them, they look good, great little wireless amp with built in Bluetooth.
Otherwise, maybe a Roland cube would be your best bet, got a feeling one of the cubes has both guitar and bass inputs…I could be wrong. I’d highly recommend the Thunderverb though, HIGHLY.
