1590a - Downside Up FV1

PCB Only - Just the plain PCB

PCB & FV-1 – Plain PCB & unsoldered FV1 chip

PCB & EEPROM ­– Plain PCB and programmed EEPROM

PCB, EEPROM & FV-1 – Plain PCB, unsoldered FV1 chip and programmed EEPROM

PCB & Components – Plain PCB, unsoldered FV1 chip and programmed EEPROM, onboard components and any pots and toggle switches.

PCB & Components and off board parts - As above with off board components (foot switch, Jacks, 9v socket, LED)

Full Kit - As above with undrilled enclosure.

Full Kit & Drilling - Full kit with drilled enclosure.

 

Drilling is an optional extra for the Full Kit. There is a small surcharge for this.

 

Drilling includes all the holes for a complete pedal.

You will need 3 knobs for this kit. I suggest you get skinny sized.

Please be sure to read the build document before you order. The kits are enjoyable but can also be challenging.

You will have to identify components, calculate resistor codes and be able to solder them into place. 

All kits require full assembly and any images of completed PCBs are for reference only.

If you want the kit pre building then select this option, you must add your knobs from the knob section or it will come without any!

The pre build options is exactly that, you are buying a kit and I am doing the build for you. There are no returns accepted on these but I do give a 12 month repair warranty so should a fault be developed I will repair it.

The Spin Semiconductor FV-1 chip is a complete reverb solution in a single IC. Its incredibly clever, to say the least. 

With integrated stereo ADC and DACs, the FV-1 can be treated like any other analog component in your products signal path.

The FV-1 can access a total of 16 programs, 8 are built in to 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 create 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 DSP module's 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. Integrated digital LFOs and ramp generators allow for programming chorus, flange and pitch shift

Building a pedal in the 1590A size category can be challenging for several reasons:

 

Size Constraints: The 1590A is a very compact enclosure. Its small dimensions limit the amount of space available for components and wiring. This makes it difficult to fit all the necessary electronic components and connections inside without causing overcrowding.

 

Component Selection: Smaller enclosures require smaller components and thoughtful placement as you build.

 

Wiring Complexity: In a compact enclosure like the 1590A, the wiring must be meticulously planned and executed to ensure that components are connected correctly without creating a cluttered mess. This requires careful routing and soldering to avoid shorts and interference.
