PreBS 20+ Green Levant #2

patsweet — Fri, 23 Sep 2022 23:43:51 +0000

Recently completed PreBS 20+ in Green Tolex with large check Marshall style cloth. A classic look with all the tone you could want! Normal channel has tweed Bassman/JTM 45 voicing, Vibroverb bias modulated vibrato, push-pull mid boost and bright switch in both channels, user adjustable bias trim pot and test points, PPI master volume, and a 10+12″ speaker compliment. The GA-SC64 and G10 Green back are the perfect pair after testing MANY combinations. This is the new PreBS 20+ standard model. Perfect cleans and overdriven tube tones for any style music where guitar tone will stand out!

From the owner: “I haven’t gotten to use the amp in a band setting yet, but HOLY SHIT, this thing is awesome! Even my wife and her kids commented that it sounded good, instead of scurrying outside or to a different part of the house. The normal channel, set as you suggested, and plugged straight in, is probably the best driven tone I’ve ever gotten, and it is super quiet. I’m also loving the bias vary tremolo for cleans on channel 2, and the reverb knob being usable beyond 2-3. And I think you’re right, I can’t imagine any speaker combo being better than this. I can’t wait to spend more time with it, and play it with the band, but this is a grand-slam home run (and beautiful, to boot). I will be selling my reissue DR and VR without hesitation, or even a hint of remorse.”

PreBS 20+ Green Levant

The latest PreBS 20+ has a couple of new features to add improved performance and even more versatility. Along with the 2×10 speakers, over-sized transformers from Mercury Magnetics, and bias test points on the rear panel, this one also has Vibroverb style bias-modulated vibrato and Bassman/JTM 45 voicing for the normal channel and a PPIMV on the rear panel for getting dirt/grind/overdrive at reasonable volumes. This amp does both sparkling clean blackface reverb tones as well as crunchy sustained tweed/early Marshall overdrive. Too much fun! Stay tuned for some pro demos soon!

JTM 45 Build Purple Head and Cab

patsweet — Sun, 16 Aug 2020 22:38:17 +0000

This one off/prototype build request was for an offset Marshall JTM 45 style head and 2×12 half stack with a Marshall/blackface Fender hybrid circuit with master volume. The 4 jack normal/bright inputs was kept but adjusted for less extremes. The Sweetened version has two very usable channels independently or when blended via a jumper cable between inputs. Other customizations include a blackface style phase inverter circuit and full range negative feedback control instead of the traditional high frequency presence control as well as custom tone stack values for a more full range of adjustment rather than the focused midrangey voice of the original JTM circuit. A PPIV master volume completes the package giving the ability to adjust the gain from clean to crunch and beyond from bedroom to stage volumes. This sexy beast excels equally as a straight in tone machine or modern pedal platform! The control panel is labelled TLA 45 for the owners initials but it is affectionately known as “Grimace”.

This build turned out so good that it will be added to the Sweet product line! Any color is available but I think purple is definitely the coolest!
