Carl's Custom Amps British Overdrive Plexi 50w+ (2023) British Racing Green MINT!

Amazing amp, truly an incredible head with everything you'd want from a Marshall plexi (actually, 3 different plexi's!) extremely well designed, well thought out, built like a tank and sounds absolutely stunning.

In beautiful British Racing Green tolex.

110V_UK buyers will reciecve the step down transformer also

This one has all the options - London Power Scaling (one of the best power attenuators out there, crank it up for the full tone, but listen at home/bedroom volumes), Power Sag (brown sound/variac type adjustment right on the front with a knob!), the 50w+ version, which has 4 power tubes (like a standard 100w) so you get the full feel of a 100w amp, without the blistering volume.

It has the bright and normal channels "linked" internally, no need to patch multiple inputs, you get the blend by simply adjusting the Vol of the Bright and Normal channels to taste.

It has the '67, '69, '71 switch to achieve the world of different plexi tones - from clean plexi (Hendrix, SRV) to rock crunch (EVH, AC/DC). It has a super quiet internal fan to keep those 4 power tubes happy. So well thought out and constructed.

Description

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. The British Overdrive 20W,50W and 50W+ (50W but with four power tubes for 100W feel) amps are far more versatile in terms of volume the original amps were!  London Power Scaling 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.

Flexible Tone: 

  During the 60's and 70s Marshall produced many  Plexi models with very minor circuit variations that made a 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. You can get all the tones in your head! 

London Power’s Power Scaling:

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 Power Scaling which solves this issue. Power scaling allow the player to dial in anything from full power down to 1/10W.  So these amp are capable of playing anything from 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.   

Other Features:

Linked Input:  

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.  

Tube Swapping:  

The 20, 50, and 50+ 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. The 20W and 50W versions use two power tubes. The 50W+ captures the tone and feel of a 100W power section with four output tubes but only puts out 50W. You can also pull out two of the power tubes for 50W amp feel.

Spec/Features:

All tube,  Bright and Normal volume controls,  treble, mids, bass, and presence, power and limit controls,  ON/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. 100 Watt model is fan cooled.
