I am just starting out playing bass. Right now I am using the iRiffPort on my iPad with the PocketGK app. Its pretty cool but definitely not like a real amp. I think I don't want to buy a small practice amp only for it to be too little when I start jamming with other musicians. I was looking at some 500w combos and they will definitely be out of my price range. What are your thoughts on used amps? Back in the day when I would buy stereo equipment I would NEVER EVER buy a floor model speakers because of the abuse they normally took. So going into this I am thinking the same way. However not knowing much about bass amp durability, is it a bad idea to buy used combo amps (or cabs for that matter)? As always thank you for your opinions as all are much appreciated!
