The Sound Semiconductor DAB2140 is a pre-soldered DIP converter for the SSI2140. This board features the SSI2140 and two decoupling caps for the V+ and V- inputs. The pinout is labelled on the board and matches the SSOP pinout. This adapter features a 20 pin DIP base with a .600 in. width. The pins are standard male headers so 2.54mm female headers are recommended for socketing the board. For the SSOP version, please see P-Q-SSI2140. A refresh of a classic design, the FatKeys™ SSI2140 preserves mojo of the beloved SSM2040 and adds temperature compensation of gm cells and the exponential control port. A "Q VCA" is provided to allow easy resonance control as well as various options for Q compensation.

A great digital reverb sound that easily replaces a spring reverberation unit. Stereo outputs may be summed for mono operation. Simple interface: input, output, +5V, and ground

The Spin Semiconductor FV-1 is a complete reverb solution in a single IC. With integrated stereo ADC and DACs, the FV-1 can be treated like any other analog component in your product's signal path. The FV-1 can access a total of 16 programs, 8 are built into the internal ROM and the designer may elect to connect a serial EEPROM with 8 additional programs. By using an external EEPROM, the designer can distinguish his product from others by creating a custom program set without the need for a microprocessor in the system. With 3 potentiometer inputs, programs may have real time variable parameters such as decay time in a reverb, rate and depth in a chorus or frequency in a filter. These inputs are available as coefficients to your program and may be used independently of each other. The rich instruction set allows users to program effects of all kinds. With instructions like LOG and EXP, users can easily program audio expansion and compression routines.

FXCore from Experimental Noize is a DSP designed for creating audio effects in pro-audio devices. FXCore can operate as a standalone device when paired with appropriate CODECs where it generates all necessary clocks or as part of a more complex system where it will lock to the word clock and bit clock provided by another part of the system.
FXCore can store up to 16 programs and their associated register preset values in its internal FLASH memory so no external program storage is required.

Metal Film resistors consist of a resistive element of an extremely thin layer of metal alloy vacuum deposited on a substrate. Precise and quiet.

The Accu-Bell Effector offers reverb, chorus, and delay with adjustable setting and tap tempo. This module runs on 5.5V to 9.5V DC so it is easy to incorporate into effect pedal builds. Please see the attached datasheet for an example schematic.

This is a set of two 2N1309 germanium transistors that have been hand-selected to work in the germanium Fuzz Face circuit. Also included are 4 metal film resistors to use in the circuit. In most cases, the values have been modified from the stock values slightly to ensure that the collector of Q2 biases to roughly -4.5V. A data sheet containing the schematic and the resistor values is included so that you can use your own resistor type if you would prefer. There is a range of bias voltages that can sound nice in a Fuzz Face, and voltages in original units varied. These transistors have been tested with bias voltage, sound, and noise level in mind. Note that due to a variety of factors such as battery/PSU voltage, temperature, and component tolerance, the voltage on the collector of Q2 may not measure at exactly -4.5V, but it should be close in a properly-built circuit.

The LEHLE TRANSFORMER MZ is the ideal component to avoid hum loops without degrading the sound. It achieves this through galvanic isolation of low to mid impedance audio signal sources. It can be used as an input or output transformer, for balanced or unbalanced signals.

The Lehle Transformer HZ is the ideal component to avoid hum loops or to balance and unbalance signals without degrading the sound of high impedance signal sources.

The SSI2130 offers unprecedented performance and features, but its ultra-compact QFN package can present prototyping challenges. The EVB2130 eases evaluation by providing a PCB that allows comprehensive exploration of capabilities. The EVB2130-P is fully populated and ready for the bench. With the exception of the SSI2130, all components are through-hole for easy construction and experimentation. A on-board +5V regulator and 2.5V reference simplify external power connections, and pots are provided for mixer control, PWM, and VCO setup. Switches ease selection of saw ramp direction plus Through-Zero and Pulse Modulation. Features
