DAPPER SNAPPER v2

- Overdrive/distortion with gain, volume, treble, mids and bass controls.

- All three tone controls are active cut and boost circuits. Flat response with controls at 12 o'clock.

- Press and hold the footswitch to switch between medium and high gain circuits. 

- Soft switching: no loud clicks. The analogue signal is fed through a digitally controlled relais, allowing for a silent momentary footswitch and keeping the pedal true bypass. 

- True bypass.

- Red LED indicates the high gain circuit is on, orange LED means medium gain.

- The design aim was to mimic the distortion characteristics of tube amps. This circuit does not use clipping diodes. 

- Design aim two was to minimize noise. Care was taken to keep noise to a minimum, but at the highest gain settings some noise is inevitable. 

- 9VDC power supply (standard centre negative).

- LxWxH: 12,3cm x 6,5cm x 5.5cm (incl. knobs).

- 220 euro VAT incl.

Soundclips: Guitar (humbuckers) -> Dapper Snapper -> Strymon Iridium clean Marshall Super Lead and Mesa 4x12 cab. I added some echo and delay to the recording, but did no editing or equalizing. I made sure I did not overdrive the input to the Super Lead amp sim, so what you hear is the pedal's distortion only. Backing tracks: 'Bigfoot' and 'Too Cool for School' (jamtrackcentral.com).

STUTTERFLY v3

- Chopper effect.

- On/Off switch: momentary switch. Press down = effect on, release = effect off.

- Taptempo: tap the left footswitch 4 times to set the tempo. 

- Latching switching: pressing both switches down disables the momentary action and switches the effect on (bottom LED lights up). Press down both switches again to go back to normal mode. 

- Speed: manual adjustment of pulse speed. Taptempo speed is automatically deleted as soon as you turn the manual speed knob. Minimum manual pulse frequency is 0.3 Hz (speed at 0, multiplier on half notes), maximum frequency is 31 Hz (speed at max, multiplier on 16-ths).

- Multiplier: the speed knob or taptempo sets the bpm (quarter notes). The multiplier knob allows you to dial in an exact mulitple of the quarter note frequency: half notes (= 1/2 speed), quarter notes ( = speed), quarter note triplets (= 1,5 speed), eighths, triplets, sixteenths.

- Gap: adjust the duration of the pulses (the duty cycle). 

- Volume: adjusts the audio output volume to compensate for the perceived loss of overall volume when using short pulses. Up to +6db (= gain x2). This does not affect the volume in bypassed state.  

- Normal/Random switch: normal action or random pulses. In random mode you can't control the speed (or the multiplier). The Gap knob does allow you to control the intensity of the random pulses. 

- No true bypass: Stutterfly is a unity gain buffer switching in and out based on a pulsed control signal. In bypassed state the pedal functions as a non-inverting buffer.

- Frequency range 20Hz --> >20kHz. 

- Soft switching.

- Audiocircuit analogue, no DSP, pulses digitally generated. Digitally controlled switching. 

- Top LED indicates current tempo. Bottom LED indicates effect ON or OFF. 

- 9VDC power supply (standard centre negative).

- LxWxH: 11cm x 6cm x 5cm (incl. knobs).

- 220 euro VAT incl.

Soundclip: Stratocaster -> Stutterfly -> amp. Recorded on an Edirol R-09 stereo mic wav/mp3 recorder. I added some delay to the recording, but did NO editing or equalizing. The pedal sounds like on the recording  

CHIHAWWAH

- This pedal is related to the auto-wah, but it is not input level sensitive. The effect is triggered by the guitar signal and will give a consistent response regardless of input signal level. 

- The filter is a 24dB/octave low pass, with an optional resonant peak at the crossover frequency (which is shifted down or up, approaching the sound of a wah).

- The depth control allows you to set the minimum crossover frequency. 

- The resonance control allows you to dial in a resonant peak. At maximum the peak is pretty high (+20dB), so you can expect it to overdrive the input of the amplifier, depending on the gain setting of the amp. 

- Sensitivity: sets the level at which the effect is triggered. A set and forget knob for your particular instrument. 

- The autofilter has the usual decay and attack controls. 

- The direction of the filter sweep can be easily reversed by the Haw/Wah switch, without the need to readjust decay and attack controls. 

- The 'Rel' switch allows you to easily (dis)engage the release function. 

- Since the filter sweep is triggered by the input signal, the control signal that activates the signal within the pedal is reset at zero input (i.e. muting the strings). 

- Soft switching.

- Audiocircuit analogue, no DSP. Digitally controlled silent switching, with true bypass.  

- LED indicator

- 9VDC power supply (standard centre negative).

- LxWxH: 12cm x 9.4cm x 5cm (incl. knobs).

- 250 euro VAT incl.

Soundclip: Stratocaster -> Chihawwah-> Strymon Iridium Marshall Super Lead and Mesa 4x12 cab.. I added some delay to the recording.

ABY box

- Sends the input signal to two separate outputs A and B

- An active buffer circuit prevents any signal loss.

- OR switch: switches between the outputs. AND switch: switches both outputs on. 

- Output B is transformer-coupled, allowing you to electrically completely isolate this output from the rest of the circuit. 

- The left toggle switch allows you to lift output B from ground. These features provide all possible configurations to minimize any noise caused by ground loops when driving 2 amps. 

- The right toggle switch inverts the polarity of the signal at B, in case phase differences cause issues. 

- Soft switching: no loud clicks when you press the switches. 

- LEDs indicate active channels. 

- Frequency range of the isolated output B is minimum 40Hz --> >20kHz at signal levels up to 3Vpeak, which is way higher than normal non-boosted guitar or bass signals.  Signal distortion at normal signal levels starts below 30Hz, making it suitable for even a 5-string bass guitar. 

- 9VDC power supply

- LxWxH: 12cm x 9cm x 5.5cm (incl. switches).
