New US based kit supplier

This has been requested by lots of people in the US.  Bitsbox are a fantastic resource for this site supplying kits and other parts to many destinations around the world, but unfortunately the insurance requirement for shipping goods to the US became prohibitively expensive for some businesses over here and so they had to make the decision to stop shipments to the US.  Many of the visitors to this blog, in fact the majority of visitors to this blog are US based and I have been asked about kits for a couple of years now by many people, and now you can get them.

MKLEC is a small independent retailer located in Columbus, Mississippi and they have been working hard for a couple of months now to get their stocks up on the components required for the kits, and have now started putting them together.  At the moment only the Deep Blue Delay kit is up on their site, but it will be followed by the Klon very shortly and lots more to follow.  The kits will be posted on this page:

The business is run by husband and wife David and Amanda who are lovely people, and I would encourage anyone who is interested in buying kits in the US to contact them to give them feedback of what kits you would like to see first, then they can give some kits priority in putting them together.

As I said they have been putting a lot of work in getting the parts together and David was adamant that he use high quality components throughout, so the kits use Xicon 1% metal film resistors, Nichicon and Panasonic polyester film capacitors, WIMA and Cornell Dubilier for the polybox cap and audio grade electrolytics so even if you are indifferent about component types, you can be assured of quality and longevity of the popular branded components chosen.

If you have any questions then get in contact with us, or even better MKLEC directly so you can hear straight from the horses mouth.

David has sent me a kit to build and when completed this will be given away in a free draw to new customers signing up for an account with MKLEC via this blog, so when you do sign up make sure you note tagboardeffects somewhere in the registration form so you can be included in the draw.  Just pop it in one of the unused form boxes like Fax, Company or Company ID or alternatively send him an email so you're added to the list.

Fulltone Fatboost V1

Request for vero version.  Info about Fulltone's original copy of Jack's Mini-Booster circuit:

This magic little box (the size of an MXR phase 45) is for the Purist, whether you're a Guitarist, a Bassist, whether your thing is Jazz, Rock, Acoustic/Electric, or Heavy Rock.

Not a distortion box, the Fat-Boost is a Class A Discrete design offering up to up to 30db of Clean Boost without ANY change to your EQ.... and at the same time it makes your sound Bigger, with more even order harmonics! You Blues players with the vintage-type tube amps will never turn this thing off... and it works great in front of Master-Volume amps to kick them up a notch as well.           

The Fat-Boost gives you the feeling that your amp is cranked at living room volumes so clean playing is more dynamic, notes hold on longer without being distorted! 

Jerry Garcia Tiger Preamp

Request. Info about Jerry's original guitar with inbuilt electronics

Tiger was Jerry Garcia's main guitar from 1979 to 1989. It was built by Sonoma County luthier Doug Irwin. The Tiger is named after the tiger inlaid on the preamp cover located on the guitar's top, just behind the tailpiece.

The electronics of Garcia's Irwin guitars are unique, and feature an onboard preamp and effects loop. Much like a Stratocaster, the three pickups are selected with a five-way switch. Signal from the pickups passes through the tone controls, followed by an op-amp based buffer preamp, or Unity Gain Buffer, which is designed to prevent signal loss due to capacitance when long cables are used.

Fulltone Bassdrive Mosfet

And the bass version.  This is based on the guitar version but with the passive changes to match the filters in the bass version.  The diodes seem to have changed often in this, some with symmetrical mosfet/germanium combinations with a 1N34A in both directions and some with asymmetrical as shown here.  Some with more than one 1N4001 (or 4005) or asymmetrical on the silicon side with 2 x 1N4001 and 1 x 1N914.  So I'm just leaving the clipping as per the guitar version, and you can put your favourite combination in there if you choose.

Info about the discontinued original:

Bassists need dirt too! But no one, until now, has given you something that works, with all the full, rich bottom-end that you deserve, damn-it! BTW, many guitarists use and prefer the Bassdrive for Guitar!

The Bass-Drive is a lot like its cousin the Full-Drive2, but voiced with an extra octave of bass coverage... still giving a natural, uncolored FATNESS to your thang.

From just adding a little grind, to replicating a raging SVT, to sounding like Jack Bruce in Cream. (He's got one already!)


Here are a couple of other clipping options based on other schemes and notes.  The differences are 2 x 1N4001 instead of 1 x germanium diode in series with the mosfets which will give you symmetrical instead of asymmetrical clipping.  The output is switched instead of the inverting input (which shouldn't make a difference but required an extra row for me to accommodate it).  And on the third version the silicon side is asymmetrical with 2 x 1N4001 in series on the silicon side.  These have all been used so I'd suggest installing a few sockets and trying a few variations.

Fulltone Fulldrive II Mosfet

Requested by a few people. Even at 22 columns wide it could still fit in a 1590B if you wanted, and the first person to do it wins the TagboardEffects Awesome Builder of the Week award! :o)  But I wasn't too bothered about the board size because I suspect most people will want to put this in a 1590BB with two stomp switches.  The layout is based on this schematic on FSB posted by mozwell.

Info from Fuller about his original souped up Tubescreamer:

Housed in a beautiful powder coated Blue 16ga. steel enclosure, the dual-channel FullDrive2 gives you the best of both worlds. The first channel is the "Overdrive Mode" capable of clean boost or non-compressed overdrive or choose light to medium softer overdrives all while retaining your guitar's original tone. The Tone knob is a very effective presence control that can smooth out or add upper harmonics. The second channel is the "Boost Mode" with its own separate distortion control for medium to higher gains with a more singing violin-like sustain!

In 2007, the FullDrive2, the most popular boutique overdrive ever made, and staple on many pedalboards for years, became the FullDrive2-Mosfet, sounding better than ever before.

One mini-toggle lets you choose between a "Vintage" FD2 sound with mid-heavy tones that cut through the mix and "FM (flat-mids)" for a more natural, transparent sound that works awesome with a Strat's neck pickup.

The other mini-toggle lets you choose between Mosfet and Normal clipping modes. Normal mode is even more asymmetrical, sweeter and more open, with no "blanket" over the sound.

And, of course, the FD2-Mosfet features super-bright LEDs (borrowed from the OCD) and Fulltone's exclusive "no-thump/no-pop" True Bypass switches. We are the first to offer a switchable "Boost" Channel in an overdrive and manufacture our own Super-Duty 3PDT footswitch allowing True-Bypass plus LED.

Chosen by Guitar Player Magazine as "Best Stompbox of 2006" and as one of the all-time top 50 effects ever!

I wasn't a great fan of the asymmetrical mosfet and 1N34A diode configuration in an OCD version 4, which quite frankly I thought sounded like ass.  So I've done an alternate version based on symmetrical clipping with 2 x 1N4001 instead of the germanium diode.  This has been noted in some versions of this pedal and was definitely used in the Bassdrive so I think I personally would opt for this version even if it's a row taller.

Should all layouts be verified before publishing? This would mean less layouts but more peace of mind?
