I have a weird problem with my bass guitar and I wanted to have some sort of background knowledge before I bring it in so I understand what the repairman is saying and/or so I don't get taken.
I have two bass amps. A 350W "performance" amp and a 10W practice amp. When the bass is plugged into the 350W amp, the sound/notes it makes is very, very quiet, even when I turn things all the way up on both the amp and the bass. I should note, there is a passive and active port to plug the cable into and this is happening for both ports, although, most of my initial testing was with the passive port.
I tried 3 different batteries (new and tested to be strong) but the sound is still very low.
I borrowed 2 other bass guitars from friends and they sound nice and loud on the 350W amp so I think the amp is good.
I plug in my bass into the 10W amp and it's nice and loud (or as loud as can be on 10W). I also plugged my bass into my friend's 50W keyboard amp and it also sounds nice and loud (for a 50W amp).
With all this said, what might be wrong with my bass since it seems to work on some amps but not others? I haven't taken the bass apart yet (don't trust myself) so I don't know if I'll see something obvious (like a burned out component that's burned brown). What should I keep my ears out for when the tech is finished examining it and tells me what needs repair?
My bass is a Ibanez SR405QM 5 string guitar.
The troublesome amp is a SWR Black Beauty 350W 15" amp.
The practice amp is a Crate BT15. My mistake, it's not 10W, it's 15W.
One friend's bass is a Yamaha RBX765A 5 string guitar. It also uses a battery. I forgot the other friend's bass b/c I had to return it =(
