+1 to what the above fellow Silkynites have said. Also, with most experiences, it will require a matched set of output tubes with a bias check/adjustment as all 4 of mine have been very mismatched. I consider that maintainance anyway. I have done mods to two & the other two are stock.
Once all that is done..you are golden.
They are my favorite amp. One of them goes with me always to Jam Nite, gig whatever. I also have a Delta Blues 1X15, but the Silkyn outperforms anything else I have played through in my somewhat limited experience.
I will probably end up selling at least one of them after I receive the PT, but I will always keep at least one. If I do sell, it will include the new PT, new output tubes, & either modded or stock per the buyers wishes. Gotta get the PT's in first though.
