Well my 6L6 version has much more gain than my ex DC5.
Ive bought my 50+ just as an amp for few gigs until ill get DC5, when DC arrived, ive put 50+ for half year to basement. Ive also decided to sell it, but before the guy arrived, ive wanted to check if is everything in order. So ive turned 50+ on and from first note, i could say : What have i done!!. The tone was totally perfect, of course ive played it few times before, but i dont know why, it fitted me now sooo much. And well, its my main amp till these days. No i run there NOS 5881 and in preamp combination of lot tubes. And to be honest, ive compared it to lots of amps (MkIII,MkII,DC5,DR,SR,Marshalls, local boutique Rockwell, Rivera etc.) and every time it makes me sure that i should be happy to be owner of such a great amp. Just one weakness is on control for both channels, but you can get use of it and it learned me how to work with volume in guitar or use volume pedal...
i play post-hc/crossover, not these with noise tones, but more melodically, with pretty long passages, i use PRS McCarty Soapbar and im happy every time i play it, it never dissappoinet me...hope it wont...
and to compare with DC the DC had not so much balls, not so raw, not so truthfull :d more modern amp...
