PreBS TT40

The first Sweet Low Power Tweed Twin build is completed! This is one of the most unique and  interesting Fender tweed era models with dual rectifier tubes, a unique pre-amp circuit, cathodyne phase inverter(like tweed Bandmaster and Princeton Reverb),  and a quite large output transformer for a pair of  6L6 power tubes. As always, I’ve added a few extra features for versatility like separate pre-amp cathode resistors and caps for less interaction between channels and the ability to use different tubes for each channel. I’ve also added a gain switch for each channel, push-pull brite switch for each channel, bias trim pot, and a negative feedback switch.

The result is a beautiful touch sensitive tweed tone with lots of character and compression when pushed. Well suited for any rootsy musical genre! Output is 25W-45W depending on power and rectifier tubes used but sounds best to me with the stock dual 5U4G and 6L6GC combination.

Tube Cage for Fender Blues Jr and Pro Jr

As an amp tech for several decades, I cant tell you how many broken and bent tubes and damaged sockets I’ve seen in Blues and Pro Jrs. The new III version comes with a  cage but it is not available as an accessory. So, at the request of a regular customer, I made a couple of protective tube cages and then decided to make them available to everyone.

They are available to purchase on Reverb.com or if you are in the Chicago area, you could buy direct from me at Chicago Fret Works/Amp Works, 4229 N. Lincoln Ave, Chicago IL 60618   773-698-6246

McKoustic 30 combo

Introducing a new Sweet combo for acoustic instruments, the McKoustic 30! Another McKeever collaboration with my dad who built the cab from solid cherrywood and finished with hand rubbed oil/urethane. The sealed and ported cab features  full range Eminence 10″ and 3″ drivers for a natural reproduction of your acoustic guitar, mandolin, guitaron, uke, or violin.

The pre-amp has been tuned specifically for acoustic instruments and features a feedback control section with selectable frequency and level control as well as a push-pull bass cut and push-pull bright control.

Tested with a passive K&K equipped boutique guitar as well as a modern Seagull with active Fischman pickup and pre-amp system. This amp will sound like your guitar but louder! Bring your acoustic guitar/instrument for a demo to Chicago Fret Works before the client pickups it up!

* This is also the prototype for a similar all tube bass combo combo coming soon!
