Engineering the perfect overdrive...again! (And this time we brought a friend.)
There is something special about a Keeley Modded Blues Driver. There's something even more remarkable about Andy Timmons' tone. Since his exposure to this Keeley modded stompbox early on, it has been virtually glued to Andy's board. So, what happens when Andy and Robert use the familiarity of the Super Phat Mod platform to dethrone a classic? Enter the Super AT Mod.

Andy Timmons and his beautiful guitar playing have been known to bring people to tears, literally! After working with Andy for a couple of years Keeley decided to focus his ears on the Keeley Super Phat Mod. There are two significant modifications to the tone of the Super AT Mod Overdrive that will be very apparent to players. The new Timmons mod accentuates both the tone control and the gain creation making this circuit truly sound and respond like a tube amplifier in a stompbox.

New Tone Switch
There is a new circuit design for the Tone Switch in the Super AT Mod Overdrive. The AT-mode is voiced for humbuckers. The new AT-mode features lower mid-bass frequencies so your humbuckers sound tighter and more transparent. Like Andy says, "I just wanna play melodies all day"; the Super AT Mod Overdrive inspires you to play guitar!

If you have single coils and want a little more power behind your sound, the original Keeley PHAT-mode is still available with the Tone Switch flipped to the right.

Asymmetrical Tube Clipping
The most dramatic change to the distortion characteristics of the pedal is with the clipping diodes. The new Super AT Mod Overdrive features a return to the RK's original clipping style, a 20 year old modification first performed in the Keeley Blues Driver Phat Mod. For this AT edition we create asymmetrical clipping by using a combination of regular diodes and LEDs. Light emitting diodes (LEDs) clip or distort the signal at a higher voltage than do regular diodes.

Asymmetry enhances the tone by giving your ears something a bit more interesting than a basic square wave to listen to. Tube biasing, output transformers, and the balance in a push-pull output section, can cause natural asymmetrical clipping. The Super AT Mod Overdrive pedal exhibits the characteristics of a pushed tube amp. Andy's chord work and harmonies are cleaner and tighter now, without reducing any gain.

Super Amp Tone In A Box
If you want an drive pedal that responds just like a tube amp, the Super AT Mod is for you. The topology of the pedal is similar to classic California tube amps, Keeley simply use JFET transistors in place of tubes. Nothing has been left out, even the filtering of an amp's tone stack is designed into the pedal. It's an amp-in-a-box, only better because it's Keeley developed with the guidance of Andy Timmons.

Features

• Andy timmons inspired mod

This one is my new favourite dirty boost. Works great if your style is to boost into a mildly breaking up tube amp. I do this: Set up the amp for a home sound (clean/breaking up a bit) with the guitar on 10. Set the peddle with gain at 9 or 10 oclock. Turn guitar volume to 7 or 8. Crank up pedal output until it sounds about the same level with pedal on and guitar at 7/8 as it does with pedal off and guitar at 10. Leave it on and use the guitar volume to control your sound. I have a comp at the end that also works great if you want more range from the guitar vol without losing actual vol. I can compare it to a klone tumnus. I would say the klone is smoother and more mid bump. This AT breaks up more like a fender when you add more gain, doesn't have that mid hump, still trims the low ends a bit, and it has a very sparkly top end. It can wake up a dark pickup or give you that 3rd album Hendrix giant blues tone. I don't like the light right above the middle knob. You need to be standing on top of it to see if it's on. I don't like the red/white metal knobs because when you can see the light it scatters off the knob face making it near impossible to see the knob setting. I swapped the knobs for the first time on any pedal due to this. Love it.

Performance Warranty Banner

Protect your investment with the Long & McQuade Performance Warranty

A warranty can be a very important factor when making a buying decision. Because repairs can be very expensive in terms of parts and labour costs, manufacturers usually only provide one year limited warranties that generally only cover items that malfunction due to a manufacturer’s defect. With an important purchase such as a musical
instrument or piece of studio gear, however, many people want to have the peace of mind in knowing that their investment will be protected should the product no longer be performing at 100%.

Because of this, Long & McQuade provides our customers with a FREE one-year Performance Warranty on most of our products. The Long & McQuade Performance Warranty supplements the manufacturer’s warranty to ensure that our customers receive complete “no hassle” warranty coverage within their first year.

How does the Long & McQuade Performance Warranty differ from most manufacturers' warranties?
  • Performance Guarantee: Normal wear and tear is covered, so your product will be performing as well as the day you purchased it for the entire duration of the coverage. Band and Orchestral Performance Warranty does not include replacing pads or cleaning for woodwind instruments, unless deemed necessary by our repair staff. Ultrasonic cleaning for brass instruments will be provided if deemed necessary by our repair staff, but is not routinely offered under the Performance Warranty.
  • Product Replacement: If your product cannot be fixed or costs too much to fix, we will replace it with the equivalent model for no additional charge. If this is not possible, a full refund will be provided.
  • No Lemon Policy: Your product will be replaced should the same problem occur multiple times.
  • Convenient: Easy drop off and pick up of the product at any Long & McQuade location.
  • Guitar Setup: Guitars purchased at Long & McQuade come with 1 free setup, to be redeemed within 1 year for new guitars and 90 days for used guitars.
  • Loaners Available: A loaner product may be given while the product is being repaired.
  • Power Surge Protection: Your product is covered even if damaged from a power surge.
  • Accessory Coverage: Any peripheral devices or accessories that come with your product (i.e. foot pedal, case) are also covered.
  • Commercial Use Coverage: Music and recording professionals who purchase gear for “heavy-use” commercial purposes will still be covered.
 

Long & McQuade reserves the right to restrict the purchase of additional years of Performance Warranty. Used products come with a 3-month Long & McQuade Performance Warranty. Some products (i.e. computers, software, cymbals and other items) are covered only by the manufacturer‘s warranty. Consumables (i.e. strings, reeds, drum sticks, batteries, tubes, cross faders) are excluded as they are designed to be replaced. Cosmetic Damage, Accidental Damage, or problems caused by Humidity or Temperature Issues are not covered. Speakers damaged by overpowering are generally not covered. Our coverage does not provide compensation for loss of use. As of June 2018 the Performance Warranty is no longer transferable. The warranty is only valid in Canada.

Purchasing additional years of coverage

Some manufacturers provide warranties for longer than 1 year; however, these are usually limited warranties that do not provide the same coverage as the Long & McQuade Performance Warranty. Customers interested in more complete and convenient (but not necessarily longer) coverage are still able to purchase additional years of the Performance Warranty.

If you are interested in receiving this coverage for longer than one year, you have the option of purchasing additional years of the Performance Warranty. The pricing is as follows:

  • NEW products: Starting at 4% of the current new selling price to double the warranty from 1 year to 2 years. Starting at 4% for each additional year.
  • USED products: Starting at 4% of the current new selling price to increase the warranty from 3 months to 1 year. Starting at 4% for each additional year.
  • GUITARS: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year. $45 maximum. An additional free setup is not included with additional purchased years of Performance Warranty.
  • BAND and ORCHESTRAL instruments: 4% of the current new selling price to double the warranty from 1 year to 2 years. 4% for each additional year.
