- added FET buffer. Optional to build buffered or non buffered version.
This creature will "smootherns and sweeterns the tone to give a fat and clear bass tone. It give fair amount of gain to your line level input"....you know what is this if you are a keen bass player. :)
Folk Fuzz Deluxe 3.5 Transistors are layout as what delivered: - T1~ T3 = 2n2219A CAN package (T1,2 = 2n1306 ; T3 = 2n2219A on the schematic) T4 = 2n2905 (To-92 package as delivered, Can / TO-92 can be used in with this layout). D2, D3 are 2n914 D4, D5 are 1n4001 D2,D3 & D4,D5 are selectable clipper thru SPDT switch.
Fuzz knobs is B1M, preferably C1M according to the Bjorn. Tone is A50K, Volume is B100K.
Trembo Tremolo - Pending Tremolo. JMP = JUMPER WIRE VTL5C1 = optical isolator. Control is KNOB and RATE. Trimmer is to adjust the OPTICAL LED intensity. LED beside trimmer is on-off indicator, connected to LFO to blink according to the LFO rate. Familiar eh....pm me to know which TREMOLO this is modelled after.
Transformer-less DI-BOX This box operate with 18v but i think can work with less voltage. I create this to use with YAHAMA EMX5000 PA system to try a simple recording. XLR is the balance output to be connect with XLR socket. The square pad is the first pin, middle being the pin 2 and the last round pad is the pin 3. SPK/LINE is the selector to switch LINE output or SPEAKER output. Can be modded to operate in PHANTOM power mode.
Plush Envelope Filter All Diodes are 1n914 or equivalent. All film caps have 5mm pitch. OP AMP type is not critical. Any dual OP-AMP will work great. SPDT is to change the sweep UP or DN; UP has very little effects.
Elley Mammoth (Bass Fuzz) Transistor is 2N5089. Pins compatible with 2n5088. 2M2 Resistor and the 100uF (Power Filter Caps) above 20k Resistor is not in the schematic. They were added for stomp pop elimination if needed and caps is for better power filtering.
D'Queen Treble Booster. Size of Board: 37mm Width x 3mm Height (1590B Box okay!) B2K can be omitted if the gain control is not needed. Use 2k4 ohm in this case. If B2K is used, use a smaller resistor here. 470R is a starting point.
6k8 to 10k resisstor can be used in the the third resistor from right in bottom row.
Use 2k2 resistor in the last resistor from right in bottom row if the Super Bright Resistor is used.
These PCB are my own work from the schematics share on the net.
The ownership of the circuit / design remain to their respective owner but the layout / pcb artwork are MINE.
