these basses are awesome, I have 2 of them one is the charcoal burst the other is tobacco burst. depending on the condition $350 is a good price. I have all the modules, the best ones are the filter follower,phase shifter,flanger,octave unit. check out the electra mpc web site,great info on the history etc. you can find the modules on ebay but depending on the module they can go for a lot of money.
