Headphones amp for pedalboards & rehearsal (with mp3 AUX in).

This is a full stereo mixer with a headphones out. The standard input can be used to connect the signal from your pedalboard (stereo or mono) and the AUX-In can be used to connect a phone/mp3 player/sound card line out or other similar device.
Both inputs are mixed and routed to the headphones out to assist you on a “silent” rehearsal.

The device is also equipped with a TRS THRU output, this way whatever signal is routed to the input can also be picked up by any other device you’ll connect to the THRU output (like an amp, or another pedal) and it will remain unaffected because of the very high input impedance of the device’s buffer.

Internally a separate mixer circuit converts the Stereo Input signal to mono and routes it to the balanced XLR output.
The input volume control does not affect the level of the XLR out. The AUX-in signal does not output to the XLR.

- ST/M Toggle switch: allows you to select the type of signal (Stereo or Mono) that is being routed to the input. If you are working with a mono signal this toggle switch ensures that you will be hearing the same mono signal in both L+R channels of your headphones.

3 knobs:
- Input Volume knob
- AUX-IN volume knob
- Headphones-out volume knob

If any of the Input signals is too hot and causes distortion to your headphones just attenuate it from its respective volume knob.

Triple Loop Parallel Stereo Blender [V3.0]
This is an all analog Stereo Blender that offers three independent parallel loops with tails capability, stereo/mono selection, dry blend,
master volume control and an indepedent Headphones-out with volume control.
Every loop has its own dedicated footswitch, Send/Return volume knobs, EQ, and phase reverse switch.

The device is able to handle signals varying from instrument level (guitar, bass, etc) up to higher line level (~24Vpp max). All jacks are TRS. It is compatible with mono signals as well. Mono FX-Loops can be combined wth Stereo FX-Loops.

--- Technical specifications:
▹ True Bypass (via analog IC switches, requires power)
▹ Supply Voltage required: 9V DC (center negative).
▹ Current draw: 280mA
▹ An internal circuit module provides the necessary Dual Rail voltage,
for maximum headroom and stability.
▹ Input signal level: up to ~24Vpp
▹ Input & Return impedance: 2MΩ
▹ Output & Send impedance: 100Ω
▹ Flat response on the whole span of the audio frequency spectrum.
▹ Master Gain: +6dB(V)
▹ Weight: 1.1kg (aprox.)
▹ Enclosure dimensions: 242 X 127 X 52mm (9.50 x 5.0 x 2.04 in.)

4-way splitter/switcher with ALL Outputs ISOLATED.
Active, buffered, suitable both for bass & guitar or any other instrument with similar pickups.
It features high input impedance and very low output impedance in order to preserve your tone and to not degrade your signal.

Every output is equal to the input (zero volume drop) and is isolated each with a dedicated audio transformer. Each output has a dedicated foot-switch (+ LED) so that you can turn them ON/OFF on the fly.

The splitter can be powered with a variety of voltages ranging from 9V up to 24V max. Larger voltages offer you more headroom so that you can
also use it with higher line level signals.

All output jacks, including the DC-jack are placed at the top-side of the enclosure and the input jack on the right side.

▹ Input impedance: ~3.3MΩ
▹ Output impedance: ~330Ω
▹ Voltage required: 9-24V DC
▹ Polarity: Center negative
▹ Current consumption: 10mA @ 9V
▹ Enclosure dimensions: 120 x 95 x 35mm (4.72 x 3.74 x 1.37in)
▹ Weight: 440gr

dOTRsmoker, a FET pre-amp inspired by the Orange OTR-120 circuit.

The idea originally was given to me by a friend guitarist that was experimenting with various pre-amps. As a fan of the OTR-120 he suggested that it would be a nice option to have a transistor based reproduction of the OTR's pre-amp in a pedal footprint. And... here it is!

While many builders tend to call it "tube emulation" I am not a fan of this term despite the fact that many people out there use it.
The goal was to build a FET-based circuit with similar topology, same controls, with a frequency response close to the original pre-amp and
with a relatively high-gain capabilities.

The parametric EQ (Bass/Treble) is exactly the same as in the original circuit and the Presence control was implemented in a similar way, originally in the triode's cathode, here on the FET's source. The F.A.C. (Frequency Attenuation Control) behaves in the exact same way while minor changes have been made to the capacitor selection in order to maintain its flexibility similar to the original.

A voltage doubler has been added in order to provide the FETs and the circuit with the necessary headroom and gain range.

The circuit has been tuned for gain-oriented use and even with the gain knob at minimum position the sound doesn't clean up completely but it has a slight grit and goes up to high gain levels when turned to maximum.

dOTRsmoker is actually an all-around drive/distortion pedal with great range and flexibility. We designated it as "pre-amp" because its design
was based on a pre-amp and of course it can be used as one since it provides more than enough output volume especially in high gain settings
and can take other boost/drive pedals in front of it if you want to push it.

- True bypass
- Voltage Required: DC 9 Volt (voltage doubler inside)
- Polarity: Negative tip
- Current consumption: 8mA
- Enclosure dimensions: 120 x 95 x 35mm (4.72 x 3.74 x 1.37in)
- Weight: ~360gr
