Have been playing real tube Marshalls since the 90s.
Bought this from Sweetwater just before Christmas so have had it for about a month.
Saved the box to return because it was so expensive in case I did not LOVE it.
Was looking for a hand wired boutique amp for home and some gigs. This is expensive for Marshall but relatively inexpensive for a boutique amp (and it was hand made by the company with probably more amp experience than any other).
Materials and finish are top quality.
Range of sound is fabulous. KT66s deliver shimmery cleans that are punchy when you have more pick attack. The Gain and Master Volume deliver that amazing Marshall OD sound at volumes that are tolerable for gigs or at home without attenuator.
Built in effects loop is seamless with boost pedal - reverb and other effects does not change one bit.
I usually set the gain at 50% to 75% and roll back the volume on the guitar to get nice warm cleans. The boost is really like a second channel and a simple execution of what you need to switch from rhythm to lead.
The 30W to 5W switch works as expected making the breakup happen sooner.
Paired this with 2x12 cabinet for nice full sound.
With a five year warranty, attention to detail, Marshall reliability and all of their expertise building classic tube amps, how could you go wrong.
It sounds just like excellent Sweetwater review.
