I sent my Bogner Twin Jet to Fortin for the ultimate mod for the Twin Jet
Basically, I told him to mod the snot outta it.
I want the amp to be tighter, pissed off with a boosted tone with many other changes.
Here's what Mike came up with:
To recap, your Twin Jet was basically rebuilt, all the control pots on the front of the amp
were replaced, rewired. It now functions normally.
Crunch channel(3 gain stages) was changed to a pseudo Cali inspired Marshall vibe thing.
Running the gain control very low along with the channel's presence control off and volume pot
pushed in and maxed out, yields an almost clean sound.
The channel's presence control is now like the OD channel but a different high frequency starting
point.
Pulling the volume control engages a clip circuit similiar to one of the Cali saturation settings.
Volume will change but you can make it up by adjusting the volume higher to match the OD channel.
OD channel: The OD channel was completely revoiced(4 gain stages). The presence control on the OD channelis a gain control for the treble frequency. It allows you to dial in the edge better than the original presence control.
Gain pot puched in, more traditional gain structure but still can get aggressive.
Gain pot pulled out, upper mids gain boosts and much more aggressive!
Master section: Again, the power amp was completely changed design- wise.
The master presence control is now shifted higher and brings on the true presences.
The Depth control also was changed frequency wise and now is more usable in it's sweep range of the pot.
External Dual Bias: The dual bias for the 2 outside and 2 inside tube locations.
Amp is labeled and the biasing functions the same as before except you can adjust the 2 pots on the back
panel and metering is the same.
I installed 2 Winged C 6550's and 2 Winged C EL34s. Your preamp tubes are the same( a mix of NOS and current) but placed in different orders.
FX Loop: Added the Parallel function by pulling out the send control.
You can now place your stomp box delay pedal in the loop, set it to parallel and adjust the send the send level control. Works like a charm. Very transparent and the footswitch functions the same way, no issues.
It is now the Fortin Jumbo Jet
I would like to thank Mike Fortin for his impeccable professionalism, talent and coolest dude ever'alism.
I feel blessed to have this amp and the whole experience was so fun.
I also feel like I have made a new lifelong friend.
Mike thank you so much!
