I only own a 45w att amp that I got with my bass and it sucks considerably. Anyone out there heard of "drive" amps? neither have I. im loking for a 60- 100 watt amp of decent quality and everything ive seen new is very expensive. because of this im looking for a second hand amp. why is it that amps cost at least twice as much as a good bass? i need help with how much i should pay for different size second hand amps, and any brands i should be looking out for. i dont really wanna spend to much however.
