I have recently been selling off my collection of basses and amps to buy one awesome bass and one awesome amp. The bad news is I blew a large chunk of my budget on the bass (Sadowsky Mv4, couldn't help myself). So I am left with about $700 to spend on an amp but would like to stay under that if possible. I am looking very seriously at the following USED amps (in Canada, off Kijiji) 1. Ashdown MAG C115-300. $250 (As far as I know this is a kick-ass price) 2. Ashdown ABM C210-500. $700 3. Ashdown Klystron C410-500. $600 I landed on these amps because I want something I can use to practice at home, but also transport (relatively comfortably) to a medium sized gig. I am happy renting extension cabs for one night they only cost about $10/day, and I am only gigging 1-2 times per month. I really enjoy the sound of all 3 amps, I am really looking for advice in terms of the value of each. My top choice would be the ABM, but I feel that it is overpriced because the Klystron is a "higher end" amp, newer, and has 4x10" speakers vs 2, meaning I would never have to rent an extension cab. Bad news is its 100 lbs. If it matters at all, I was previously using an old blue-carpet Yorkville Bassmaster 200. Any advice or insight would be greatly appreciated.
