I do not have an SMD heat gun. I used a regular soldering iron set at 380c. Applied some flux to the 3 pads. And dabbed at little amount of hot lead on the G pad on the PCB. The then moved the mmbfj201 while heating up the lead on the G pad. After positioning it properly i then applied some lead...

Can I use two single-gang pots in place of the dual-gang Gain Potentiometer?

Cornish G2

Metal bezel? Happened to me before. The LED leads can touch them and mess up your pedal. Slap some tape on the legs.

Try checking if the pots are soldered properly on the board on both sides.

check pin 1 of the potentiometer. Lay some solder on the other side too. Socket the transistors. You can use 6 pin round hole sockets or you can also get this https://www.taydaelectronics.com/30-pin-dip-sip-ic-sockets-adaptor-solder-type.html

Is there a way to fix the muddiness of this pedal? I've checked the circuit around the 2n5089 transistor. All my values are correct. J201 is also dialed-in on the Tight side but when I switch to Big, everything is just too muddy. Is there too much bass going into this circuit? transistor...

Get some isopropyl alcohol, old toothbrush, and a piece of cloth. Use a pick or a small flathead screwdriver to get those hard flux. Drop some alcohol and brush. Wipe them off while still a little wet or if you have Goo Gone, drop some into the cloth to clean the excess flux. Make sure that your...

Try bc549c. They are pretty easy to get anywhere.

Start with the muffler. I just turned the potentiometer around to be able to fit in a 1590b enclosure. Sweep is just reversed but works fine.

Get an older beat up amp with an analog spring reverb.

just get the smd version with adapter. pedalpcb https://www.pedalpcb.com/product/mmbfj201-jfet-pre-soldered/ aion https://aionelectronics.com/project/j201-jfet/

You can use 184LC just mind the pin configuration. I use the same transistor too.

I have ordered several hundreds of various knobs styles from tayda and never had this problem. My last order was March so... Covid19 might have shrunk them. Send them an email. So they can check with their suppliers.

One of the pairs (top-mid or bottom-mid) should be ON when the toggle is at mid position. Check with a multimeter. Select this What you need to know is which side is ON. 1 2 3 4 5 6 1-3 and 4-6 Or 2-4 and 5-6 find the correct orientation
