Modifications

Each amplifier is modified on an individual basis to obtain the best results, with the client's specific tastes also in mind. A great deal of time listening and working on the circuit until the sound and response is stellar. It is a combination of a "mod", and a "re-work" to get the most out of that amp. This does not involve adding any extra tubes, or drilling any more holes in the chassis (there are options available where that would be required). What it does involve is changing the value and composition of a large number of components across the board to compliment that particular amplifier, and spending the time it requires to really get it right.
Once I receive your amp, we'll talk on the phone (or email is fine) about what your looking for from your amp, your playing styles, as well as your guitars, speaker cabs, etc. After the work is complete, I will make you a soundclip of your amp to listen to, in case you need me to make any further adjustments before returning your amp to you.

Plexi Mod/Re-work I

I designed this simply to satisfy myself. I've spent years altering the basic plexi circuit, and changing values and component composition throughout until I heard what I consider to be the perfect plexi tone. What I was going for was a basic design that was extremely dynamic and not too compressed, allowing my own style, or someone elses to shine thru. The gain was somewhat increased, along with a more musical and earthy EQ. The amp had to clean up well just by using the volume control on the guitar, as well. I have listened to many great players thru this amp design, and they all sound radically different. I find that this type of sound exhibits a player's style and personal tone, rather than masking it. It is by no means a "magic box", but if you are someone who has tone in their hands, you will love what it does. $675

Plexi Mod/Re-work I PLUS

This is everything that a Mod I is, with an added PLUS feature that adds a nice chunk of musical gain when you want it, making it extremely flexible. Many players have asked for a higher gain option on the Mod I with no compromise at all to the original, and this is it. To place the amp in PLUS mode, simply place the guitar cable into the PLUS input jack, pull out the push/pull switch, and let it fly.Hear it on the soundclips page. $825.

JTM 45/50 Hybrid Mod/Rework I

These are becoming increasingly popular. I start with a JTM 45, install a 50-watt Heyboer Plexi output transformer, a set of EL34/6CA7s, then Mod/Rework the amp to taste. Think of it as a 50-watt Plexi, only with a tube rectifier and lower B+ voltage. More dynamic than a stock JTM45 with it's overly deep low end, but with an attack that is slightly more rounded than a 50-watt 1987x model. Works on the Bluesbreaker model, too. Hear it on the soundclips page. $675, plus $175 for the output transformer, and cost of the tubes.

2061x 20-watt Mod/Rework I

Designed specifically for the Marshall 2061x 20-watt head, this gives the amp the ability for higher gain sounds while keeping the organic nature of the amp intact. Plugging into the left channel yields a hair more gain than stock, as well as a more ear-friendly EQ. Plugging your guitar into the right channel, the gain is greatly boosted, giving you the ability to really make those EL84s sing. In this mode, the tone pot of the right channel functions as a bass control, while the left side tone pot functions as a treble control, for expanded flexibility. Comes with a master, as other Mod/Reworks do, though on this particular, model, I prefer it cranked most or all of the way up ;) Both channels can be heard on the soundclips page. $675

Plexi Mod/Re-work II

Similar to the Plexi Mod/Rework, but with a fair amount of added gain, as well as a more modern voicing. This design steps a little further into modded Marshall territory and has excellent dynamics and clarity, even with the added sustain. Please check out the soundclips page to hear it. $725

Plexi Mod/Re-work III

This is an even hotter gain style. The amp still retains the plexi-style inputs where two channels are offered side by side...one brighter and one darker...yet you get the availibilty of plenty of extra gain. The tone controls become more active, as well. Comes with an onboard gain boost, using a push/pull pot on one of the front volumes. Can also be engaged with the included footswitch, that plugs into one of the front input jacks on the four-holers. A customized post-phase inverter master is included on the rear. Hear it on the soundclips page. $775

JTM 45 Mod/Re-work I

These are really fun amps. Excellent compression and clean-up characteristics, thanks to the use of a tube recifier. Available with the master volume, though some go without it, since they are only rated at 30 watts. Please check out the soundclips page to hear it. $675

"Bluesbreaker" Mod/Rework I

Basically a 2-12 combo-version of the JTM 45. Please check out the soundclips page to hear it. $675

2203/2204 Mod/Rework

This Mod/Rework is for those love the snappy attack and drive of the 2203/2204s, and want more of it, with an increae in gain and musicality. Also comes with the added master volume in the rear, which makes the amp extremely flexible, as you have more control as to what part of the circuit you get your gain from. Please check out the soundclips to hear it. $675

I perform the Bray Plexi Mod/Re-work I, II, and III on any four-input Marshall, as well as 2203/2204 models. Basically, all of the Marshalls with six knobs on the front, and without channel-switching or reverb. The Vintage Reissue series are what I work on the most, since they are plentiful and sound fantastic when completed. Plus, you won't have to worry about changing something that may be considered "vintage". I also work on "clone" amps fairly often, as well. It does'nt have to say "Marshall" on it.

Fender Mod/Rework

I work and perform Mod/Reworks on a variety of Fender amps, including but not limited to Deluxe Reverbs, Twin Reverbs, Super Reverbs, Bassmans, Bandmasters. Because many Fenders have two discreet channels, there can be extra benefits and possibilities. Cost is usually $675

Output Level Control

You can get these done with or without an Outout Level Control. Also known as the Wife Knob, this controls the overall outoput level of your amp, and is extremely transparent. Turn it down to ridiculous levels while still retaining concert gain and tone. Free with any of the Mod/Reworks. Alone, $175
Works well on a large number of amps, even ones with existing master volume controls. The existing master on your amp then becomes a secondary gain control, giving you a lot more flexibility, as well as gain at lower volumes, if you want it. Turned up all of the way, it's the same sound as not being installed.

Dual Output Level Control

Same control mentioned above, except you get two, and use a footswitch to switch between them. Only one is functional at a time...this way, you can set one slightly louder (or MUCH louder) for a solo volume. Also is great for staying loud when you turn down your guitar's volume pot for a clean sound. Just like walking over and turning up your amp without the hassle. I use it myself and love it.

This can be installed on most tube amps. This is also useful on amps with traditional master volumes already installed. $275, including footswitch with LED.

Once I receive your amp, we'll talk on the phone (or email is fine) about what your looking for from your amp, your playing styles, as well as your guitars, speaker cabs, etc. After the work is complete, I will make you a soundclip of your amp to listen to, just in case you need me to make any further adjustments before returning your amp to you.
