I'm seriously considering buying a new amp with money from my summer job, and I'm wanting to go to my local GC to really sit down and play through several amps. I'm currently considering both Acoustic and Ampeg's mini stacks, but who know what will come up. I've heard two different schools of thought as it comes to what bass to use to compare amps though. One being "An entry level bass will show only the amp's power, while a higher end bass will improve the performance of an amp and skew judgement.", and the other being "An entry level bass will not do the amp justice, and a higher end bass will show the amp's true power." So which should I go with? Or just take my own bass to get a feel for amps using exactly what I use?
