+1 on Martamp stuff for quality . I use a Goldstar Power amp for my shop rack and it's great
Another suggestion I will happily make is try a Randall RM20
This is the 18w version of the modular amp so you can change the amp type at will
You could have a blackface module for doing Fender clean - it has a solo / boost function too
But you could also swap out the module for a tweed or a Marshall Plexi or whatever
Or even put in a high gain module to fool around with - so many options once you have the amp itself
Very versatile idea!
