I don't need my Yamaha FX500B processor anymore. It's a single rack space unit from 1990. Works great. No rack ears but it has 4 rubber 'feet'. I don't have the power supply wallwart but it takes 12vdc. Manual on CD only. I also have a Yamaha BB605 bass. It's preamp is the famed ne-1. However, it has no active bypass. This is kind of a feeler I suppose. I'm wanting to try an Aggy -3 in there but I'd have to get it 1st. Well, I guess not technically, I could pull it out and go straight to the jack but you know what I mean. Would someone be interested in it If I were to pull it in favor of an AGGY?
