For sale is my Mesa 400+, in excellent condition and working perfectly, recently serviced.
I swapped the Preamp driver valve 12AX7 for a Tungsol 12AU7 as recommended on Talkbass and now sounds so much better, included on the sale is the original valve too.
I'm also including on the sale a Custom ABY Box that makes of this amp a very versatile beast. It allows you to use two different instruments also to select channel 1, channel 2 or both together. Run your effects in one channel, leave the other one clean and mix them to taste! It's a great bit of kit.
Price? £925 with the valve and ABY box included in the price.
I'm based in Hove, collection prefered but I'm happy to post at the buyer's expense and risk.
