New Model! BFF Twenty

patsweet — Sat, 07 Jan 2023 03:52:28 +0000

The first build and new Sweet model of 2023 is complete! This portable 1×12 powerhouse combo is basically a PreBS 20 in a PreBS 15 chassis and cab. No vibrato in this one but is has a few new features which make it an extremely versatile gigging, recording, and rehearsing tool! A PPIMV(post phase inverter master volume) has been added along with a push-pull Voicing Switch on the bass pot which changes the tone stack from blackface to tweed bassman/JTM45 specs. The Blackface position has the familiar mid scoop and clarity. The Tweed position adds a bit of gain with an overall thicker tone. A push-pull bright switch on the treble pot adds chime, helps to bring old strings to life, and can be used to fine tune for single coil or humbucking pickups. And the most interesting new feature is the Bias Select switch allowing for choosing between fixed bias(like most blackface amps) and Cathode/ “Class A” bias(like many Gibson, Ampeg, Valco etc amps). Fixed bias has the familiar quick and clear blackface attack and headroom while the Cathode position adds smoothness, compression, a bit more gain, and about 30% less power. These new features allow for the user to instantly mod the amp to their preference without touching a soldering iron or drilling any holes. And as usual, you can order in any color tolex/tweed/grillcoth combination as well as choose your fave speaker or tube brand. Have it your way with your Best Friend Forever/Black Face Fender style amp!

PreBS 20+ Green Levant

patsweet — Sun, 07 Aug 2022 22:25:22 +0000

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!

PreBS 15 Brown Western

patsweet — Sat, 26 Mar 2022 03:09:28 +0000

The first build in the new Tucson shop is a PreBS 15 to match the owners other two Sweet amps! Brown western tolex with Marshall cane grill cloth, Mercury Magnetics transformers, 10″ Jensen Falcon speaker, push-pull mid boost, and user adjustable bias test points and trim pot on the rear panel. This is one of only two PreBS 15 that I built with a 10 and it turned out killer! I may have to build another just like it for stock!

Pics were before the final speaker selection. See next build for the reappearance of the G10 Gold!

SOLD!

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!

PreBS 15 Surf Green

patsweet — Wed, 18 Sep 2019 03:49:26 +0000

A new PreBS 15 in surf green with a turquoise stripe in the grill cloth! Standard power transformer with a deluxe reverb output transformer and choke filtering for just a bit more headroom than a traditional Princeton Reverb. A pair of 6V6s gives 18W output through a Mojotone BV series 12″ speaker and the push-pull bright, mid-boost, and negative feedback control gives plenty of usable tone shaping options. Vintage tone that stays tight when pushed!

SOLD!
