Guitar Valve Amplifier Kit - Fender 5F1 Champ Style   

  This is our take on the famous Fender Champ Guitar Amp from the 50s. It offers a beautifully rich, creamy sound with a lovely warm bass and mid response that you can only get from a valve amp. When we tested this kit for the first time it's sound surpassed all of our expectations and we are all super excited to share this experience with you.

  Using a high voltage DC-DC boost converter instead of the conventional power transformer and rectifier valve, this amp kit is lighter, smaller and more cost effective without compromising on the performance. Since the boost converter requires only a 12V DC input, this amp can also be used on the go, and can even be powered by 12V batteries. Our design also includes a cathode bypass capacitor on the first triode gain stage to increase the gain, this is a common modification done to the original amp and we think this makes it sound better. If you want the original sound this capacitor can be simply omitted and you will get the original sound.

  We recommend using a 12V power supply that can supply at least 5A like this one BSM1250.

LED Lighthouse Solder Practice Kit

This simple flashing LED circuit is great for learning how to solder or to polish up on your soldering skills. It uses a 555 timer in the astable configuration to flash the LEDs continuously. The rate of flashing can be changed by adjusting the variable trimmer potentiometer R2 (f ≈ 0.3Hz-30Hz). It can be powered by a 9V PP3 battery (not supplied).

The kit is supplied with Yellow LEDs by default but you can choose Red, Blue, Green or White LEDs from the drop-down list above.

RAT-in-a-CAN Distortion Effect Kit

A distortion unit based on the legendary Pro Co RAT pedal from 1978. 

  We decided to make a RAT clone to rival the original “Pro Co RAT” and the best way to do this is to use the original Op Amp that gives the RAT its unique sound, the LM308. As we have some original LM308 ICs from the 70’s in our stocks we figured we could do it and do it well. There is a small difference in the fact that the original Pro Co RAT used the LM308N (8 Pin Plastic package) and we had the LM308H (8 Pin Metal can). The 2 chips are identical in how they work and sound but they look different, we decided to celebrate this difference in our design and so the “RAT in a Can” was born. 

   Unlike other modern clones that use “similar” Op Amps that can often sound a bit muddy and bass heavy, the RAT in a Can will give you gut-wrenching harsh fuzz and an astronomically high gain, this pedal is sure to make your guitar scream like a pack of angry rats.

  We hope you have as much fun building and using the RAT in a Can as we did designing and naming it.
