ME-27 and ME-36
I own 3 Mascos that I use mainly for acoustic guitar. The 3rd, an ME-18P, was acquired on 4.11.09 and is listed above. The above models are ME-27 and ME-36, both restored to more original than modified other than connectors. Whoever owned the ME-27 before me put a toggle switch for off/on bypassing the knob on front. It now works only as a treble control. The tone of these are unbelievable. Here's the good part; my Dad found it in an estate sale about 10 years ago for $3.
