Up for sale: an all original Mu-tron III in perfect working order. I got this one as a trade-in and although this truly is a great device, I really don't need it. The serialnumber is 22035, the previous owner said it's somewhere from the seventies. It has a few marks but it is in very good condition; absolutely not abused in any kind of way. It's built like a tank, it seems it will last forever if you ask me. I'm asking 350 euro's and I am willing to ship worldwide. I accept Paypal (fees on me!). I have 100% positive Ebay feedback (soulbrother_75) and can provide internet references when asked for. If you have a bass-related item as a trade(-in), let me know what you have! I might be interested. I might add some cash for a cool jazz bass. Best regards, Werner.
