http://www.musiciansfriend.com/ampl...op-special-greta-2w-1x4-tube-guitar-combo-amp So I was thinking about picking up one of these cool little combos to use as a kick-around practice amp for guitar and to listen to mp3s around the house or at work. They certainly look sweet enough. The Greta is not too expensive, but it's actually a bit pricey for me if that was all I was going to use it for so... I was thinking that I might be able to use it for a low volume bass practice rig if I used the speaker out into one of my bass cabs (as it's pretty obvious a bass would just toast the built in 4" speaker). My cabs are all pretty efficient, so the whopping 2W this beast puts out might actually be pretty decent. Also, it has a line out, so I could run it with one of my real amps into the front end as an OD or as a preamp in the loop. I know some people on here run ultra-low wattage tube practice rigs, so I'm hoping somebody has tried this out and has any thoughts. Sweet sound? Fart city? Better to run the line out into the front end of an amp or into the effects return? Any info is appreciated.
