The TCM MAXI-Q is a dual-filter set that replaces the trad tone control in your guitar.
-No new holes required
-No batteries
-Handmade to order by TCM
-Low-Pass Filter is a finessed version of the trad tone control, inspired by the Harrison 32C console
-Midrange Contour Filter "boosts" and cuts select areas of the midrange frequencies, inspired by the Olympic Studios Raindirk Series III console and the Midas XL-3 console

With only minimal soldering you can greatly expand the tonal possibilities of your guitar in an organic way!
335 set is $280
LP set is $280
"S" set is $180
"T" set is $150

PM me here at TGP for more information. Thanks in advance!

I like this!
So one tone control becomes the low pass and the other becomes the midrange contour?


It sounds like this lets the tone controls give you more detailed adjustments?

Are the controls smooth sweeping pots or do they have click detents?

Many thanks for your questions sir!

The nature of the control layout depends upon which model we are talking about.
LP and 335 harness:
-Each volume control is replaced with the high-quality CTS push/pull pot...it acts as a volume control of course, but the switch toggles between the two filters. "Down"=Low Pass Filter, "Up"=Midrange Contour Filter.
-The tone controls are each replaced with an ALPS stacked, dual-concentric pot(s). You have one mini knob sitting on top of another.
Top knob=Low Pass Filter sweep, Bottom knob=Midrange Contour Filter sweep. Fully swept, no detents.
"S" harness:
-The volume pot is replaced with the CTS push/pull pot. Again, this acts as the volume control, and the switch toggles between the two filters. "Down"=Low Pass Filter, "Up"=Midrange Contour Filter.
-The stock tone pots are replaced with CTS pots, each of which controls one filter.
Middle knob=Low Pass Filter sweep, Last knob=Midrange Contour sweep. Fully swept, no detents.
"T" harness:
-The volume pot is replaced with the CTS push/pull pot. Again, this acts as the volume control, and the switch toggles between the two filters. "Down"=Low Pass Filter, "Up"=Midrange Contour Filter.
-The tone pot is replaced with an ALPS stacked, dual-concentric pot(s). You have one mini knob sitting on top of another.
Top knob=Low Pass Filter sweep, Bottom knob=Midrange Contour Filter sweep. Fully swept, no detents.

This guitar, my TCM Spellcaster model, is equipped dead-stock with it's own specially-voiced TCM MAXI-Q control harness. What follows is a typical photo of that model and of it's control harness.

What is NEW is the fact that I now offer newly-voiced, drop-in control harness'....featuring the TCM MAXI-Q..... that are hand-built by me for the LP, the 335, the "S" and the "T"...and....custom configurations are available too.

What you get is a remarkable "expanded rainbow" of tones from YOUR guitar, right there on your knobs, no batteries involved, it all sounds natural/organic/un-hyped......no new holes, very few solder joints...pro installation is recommended but in the majority of cases, good basic soldering skills are all that are needed!

From the vaunted old-skool "woman tone".. to gorgeous dipped-mids/wide-clear soundscapes.. to a bratty mid-forward presentation that makes a statement......all the while being able to gently, musically tweek your tone right there on the guitar...a whole subtle-to-rad "sweep"..the TCM MAXI-Q delivers.

And it is made of 100% tour-ready components...assembled/made by me, Terry McInturff.

BTW that "black firecracker" looking thing contains two wire-wound iron-core inductors, as well as a select set of resistors and capacitors. A lotta magic in the TCM MAXI-Q capsule! Handmade-in-shop by TCM.

Can you build one that will go into a 62 Melody Maker with two P90's
No problem, the basic harness being very similar to the stock LP version, the voicing on the Midrange Contour Filter adjusted slightly. The Low Pass Filter would be the same. Thank you for asking!

So does this give the full range of tonal variety available in the Spitfire, Terry McInturff? It ought to be very popular; it seems to me to be a radical improvement on the standard tone controls.

Yes, the Spitfire features the immediate predecessor to the Maxi-Q; the Maxi-Q performs the same jobs, and is more configurable to different situations.
Thanks!

Ugh I took notice when you posted those guitars and was really hoping you wouldn't be offering this seperately...
There's no cause for concern. The core sound of a TCM guitar such as the Spellcaster begins LONG before the electronics. While the "T" model MAXI-Q greatly expands the tonal palette of those guitars, it most certainly does not make them sound like a TCM Spellcaster, etc.

"If there is anybody on the fence about ordering one of these just do it lol. Seriously, it’s amazing how many different tonal and expressive nuances are brought out of a guitar you already know and love. This upgrade is a no brainer!"

He has already been incredibly patient. Back when I had Terry caster 2, even pictures were something we had to guard until he said not to. What was that 13 years ago? Solves not having a mid knob on a 55 bassman and Bruno' ug 30s...

Look up demos of the Spitfire which features an earlier version just to get a taste. I have and I want the improved version in at least one guitar but probably more.
Thanks very much. You can PM me here at TGP to get in touch.
