The British Custom Overdrive is based on the late 60's and early 70's Marshall Plexi amps that defined rock tones. Pretty much every great rock band worth it's salt has had Plexi amps as part of their sound as one time. Hendrix, Clapton, Van Halen, AC/DC, Cream, Aerosmith, Gary Moore, Robin Tower and so many more have used Plexi amps. The only trouble is that Plexi amps are made for large stages making them difficult for most guitarists to use but the British Overdrive 50 and 100 amps are far more versatile in terms of volume the original amps were. Variable power allows you to dial in the sound at any volume without losing any tone. The Multi-plex switch allows you get all plexi sounds you can imagine. Now you can have all the Plexi sounds in your head without blowing out your ear drums or buying a roomful of amps.
During the 60's and 70s Marshall produced many Plexi models with very minor circuit variation that made big difference in tone. The British Overdrive put all those sounds in one amp! The Multi-Plex switch allows you to switch between a 67', 69' and 71' Plexi and a 60's/70S negative feedback switch allow even more tonal combinations. Finally a Tube/Solid state rectifier feel allow you to have bluesy sag or rock solid low end. You can get all the tones in your head!
The 60s and 70's Plexi are incredibly loud amps and were designed for big stages. They too loud for most players to use even in a club setting. The British Overdrive series features variable power which solves this issue. Variable power allow the player to dial in anything from full power down to 1/10W. So these amp are capable of playing anything form a bedroom to a stadium. Many amps have "wattage" and "power" controls that sound unnatural. The British Overdrives is different from most of these and very transparent. Plus in any setting below full power it extends the life of the power tubes.
The amp has a linked input so there no need to use a patch cable to jumper channels. This allows you to blend the sounds of normal and bright channels just like having jumped input on the amp.
The 20, 50, and 100 Watt versions can use any of the following power tube types with re-baising: EL-34, KT66, KT77, 5881, 6L6WGC, 6L6GC, 6V6 (20 watts with these), or 6550s. Bias ports and externally accessed bias pots allows the user to swap tubes.
All tube, Bright and Normal volume controls, treble, mids, bass, and presence, power and limit controls, ON/STBY, OFF Switch, hand wired for great sound and reliability with method that shortens the signal path, super quiet grounding for low noise, special resistor selection for low noise and great tone, adjustable fixed bias, solid state rectifier.

"Carl I just wanted to drop you a line and tell you about the amp you built for me . Armed with a SG and a Stratocaster I played the amp for about three hours . I managed to coax every tone that’s been hiding in my head for the past 25 years . It’s unbelievable . It has that tone and touch that can’t be described . I couldn’t be happier . You have made a life long customer out of me . Thanks for all the hard work you put into this and thank you for taking the time to help me get the amp I have been looking for my whole life ."
"Carl I just received the amp and all I can say is WOW !!!! Incredible in every way!"
"I wanted to give a shout out to Carl Carl's Custom Amps and leave a review for both the amps he built for me.
The one on the bottom is from his British Overdrive Series, its 18w, cathode bias and I can swap in and out any octal power tube combo I want without having to have it re-biased, it was modified by Carl to have 3 different voicings, 67' 69' 71', those are based on a few legendary Marshall amp tones, it also has a Master volume and a power scaling knob which are both extremely useful for dialing in the right amount of clean headroom or gain depending on where I'm playing and how loud I need to be, it also has a switch on the back for adjusting the feel of the rectifier tube either Tube or Solid State which is very helpful for tightening up the bass depending on if I'm using single coils pickups or humbuckers, there's another 60's/70's switch on the back further enhances my option of 60's style or 70's style Marshall tones. This amp is so unbelievably versatile and I've had it for about 9 months and am still finding new ways to use it. It is so intuitive to my playing and responsive to pick attacks ,and it is a great pedal platform. I run a very simple rig and don't like to "color" my amps tone much with a bunch of effects. With a amp that sounds this amazing it would be doing myself and the amp a disservice. I love the custom cosmetics on it as well!"
