Carvin X-60B all tube Amp Head - In pretty much mint condition and has the original 3 button foot switch. This is an amazing amp which is only increasing in value. Good luck trying to find one like this in this condition let alone have the original foot switch. This is not only an amazing sounding amp but it is certainly an investment. Carvin x60b, 60 watt all-tube amp head. This is the original 6L6 model, not the EL34 reissue. Made in the USA. Sounds great, works perfectly. Built-in spring reverb. 2-channel operation. Just like the famous X100B used by Steve Vai and Frank Zappa, but with a 60W 6L6 output section instead of 100W. Has an active EQ circuit that is switchable between the 2 channels. I have owned this amp for a very long time and has only been used sparingly in a small home studio. This amp has GREAT tone and along with the built in EQ its very versatile. I believe these were made early to mid 80's although I am unsure on the exact year of this one.
