- C3 (output cap) 1uF to 10 uF, for better bypass tone. UPDATE: 4,7uF
- C25 10uF to 1uF, to make the effect tone equal to the bypass mode.
- Remove R12 or change to 1M or 2M2, the original 100K + 1uF make a "tone control" in the signal.
- Remove C16, for more high end on the effect.
See the picture:
* Use Boss schematic above to mod this Behringer stomp box.
** C9 could be reduced if there are some increase of the bass of the tone, when the effect is on.

Hello guitar4geek,
ReplyDeletehave you tested these mods yourself? any clips to share?
Thank You!
S.
Thanks for the question, I tried all the mods and after that I wrote the blog. This mod in particular, has the intention to eliminate the difference in tone when the pedal is on and off. I have used 12 behringer stomps and the signal became very degraded. The test was listening the no effect tone when the pedal was on and off, and made the changes until the difference became minimal. Sorry but I didn´t have a before and after clip.
DeleteBut you can begining removing C12 and R16, to hear the diference. If you didn't like, you can put then back. Share your experience if you decide to do.
*I used a Stratocaster guitar at the tests with 500k volume and tone pots to better hear the difference in the trebles.
If I am understanding correctly, I can just swap c3 and c25, correct? Also, did you mix up your c and r numbers in the reply? Thanks
ReplyDeleteHi, tks.
DeleteYes, just swap c3 and c25 or use some left over at home.
It's R12 and C16, sorry for the typing error.
nr 300 mod are compatible with nr 100 model?
ReplyDeleteI m not sure, because I've never opened th nr 100, but it is possible to be very alike. tks
ReplyDeleteI know this a good few years old so a long shot, but I'm trying to make my nr300 more transparent and the resistor and capacitor numbers don't match up. R12 is a 10m resistor on my board, c25 is 470pf. Any idea what the correct components are on the nr300 board?
ReplyDeleteHi, the manufactors always make changes in the products thru the years, the components works in the same function, but there are sonic diferences (diferents frequences working). I have try out 10M for R12, it was a very good shot, but i radicalized and cut R12 off, but the 10M is a great choice, even better maybe. Thanks!
DeleteFor NR300 you must consider:
ReplyDeleteBOSS NS2 BER NR300
C25 C17
C3 C11
C16 C31
R12 R28
Hi, it is very fun to make experimentations, I like at that moment, to let the stomp more transparent only. But, its good to be more radical some times, go ahead and try out... Thanks!
DeleteHi man, great job you did researching about how to improve the pedal, do you still have it?
ReplyDeleteI like to have clean tones when I need but also use a lot of distortion on my 5150.
There is how to have a good balance between gate/sustain using the mods you provided?
Since you updated did you make any other improvements?
Thanks a lot! I have this pedal, but still the same, no more upgrades. This pedal works, cutting the sound when the guitar sound decrease and remains a noise, and we can set up the speed it hapens and the sensisibility. The best way, is take care of any noise without turn the gate on, cables, path, detecting other nosy pedals. After it set the gate up with the slow time as possible and a weak sensibility. You will feel when you play and the pedal is as transparent as possible. To solve you issue, i guess, you have to use the noise gate on in the dirt sounds, and off at the clean sounds, or maybe a A/B stomp to toggle between two amps, a clean and high gain. Another alternative, if is impossible to setup this pedal to be great in both clean an dirt, use two gate pedals with diferent setups. Tks!
