Thanks for the kind words
Its the nice people here that makes these projects fun to work with.
Yes, its possible to build a pedal if you prefer that.
No need for preorders yet, in February we will release more info!

That gives me a while to come up with ideas. I think I will disassemble my last Surfy Bear verb, add the color switch and add the trem to the unit. I want to do something different and there's been so many great builds that it won't be easy. |

Can't wait for the new pedal! Until then I'm in the process of building my Duel Reverb Quilty Bear! —The Kahuna Kings https://www.facebook.com/pages/The-Kahuna-Kings/459752090818447 |

I definitely will not be integrating the SurfyTrem into my SurfyBear Reverb as I would prefer it to be a stand-alone effect that I can use even when my reverb unit has to stay home for non-surf gigs due to space considerations. If the plan is to offer the Trem in kit form, then I would recommend offering the wiring diagram for a footswitch with the kit otherwise Bjorn will be responding to a lot of PMs/emails about how to do it. The Surfer Joe version of the pedal looks so cool that I hope it will be sold in that manner. If not, I will build it into a Hammond enclosure such as the BYOC pedal kits. At any rate, I am super stoked to read about Bjorn's updates and I really look forward to any further details!!! —Lorne |

Yeah, the pedal is ideal. |

I would concur on the pedal approach; really shines in terms of flexibility. Inside that pedal things are small & crowded. Some will love the challenge. But if one's idea of building a pedal is limited to "...built a fuzz once with a sparsely populated board in a big enclosure" then a build might not be for you. I love this thing in the Brownface mode even with both knobs turned way down; when you step on it there's... I dunno... something...

Will the kit be around the same price as the fet-verb? I'm ready to be the 1st user. |

I can't wait for this. I'm considering some kind of momentary switching to make it even more versatile. |

After building the Surfy Bear (which sounds great!) I'm now looking forward to building the Surfy Trem. 1) There is a switch shown on the power supply. How can that be of any use or how would that work? 2) Why are there two LED's in the schematic? In the demos of the pedal (not the kit) I only see one led which lights up and blinks when the pedal is engaged and which is off when the pedal is off. I don't understand the possible need for a second LED. 3) There is an optional footswitch connection in the schematic. Is it optional in the sense that otherwise the only other way to turn off the tremolo effect is to turn the intensity to 0 (like you would on an amp), or is it optional in the sense that, apart from an actual on/off switch, you can wire up a 'remote' switch (like a remote reverb/trem switch for an amp)? I'd like to house this trem in a pedal and wire it up with true bypass. I know the ready made pedal is not true bypass and that there's a 'philosophy' behind it but I can still include the optional switch or turn the intensity to zero to experience non-true-bypass.

The schematic is designed for use with a power supply. Battery power can be added but you'll have to find the schematics for that elsewhere on this site. The power switch is to be used before and after the show. During the show you use the foot switch.
The LED on the board is an indication of the speed. The LED in the power line tells you if it's good to go. Thats all. Skip the last if you want, you don't need it.
The foot switch switches the oscillator on and off. The LED will turn off if the oscillator is turned off. I don't really understand what you mean by a remote switch. Isn't that the same switch with a longer piece of wire?
No.
That could work. No issues as far as I can tell, except for the fact that I don't know if the switched off LED will affect the working of the oscillator. Good luck! Last edited: Jun 28, 2017 10:47:57 |

Thanks Frank for a good reply Regarding the led, I just want to add; its perfectly ok to switch the led as shown on your schematic! |

Ok, good to know, this means I could also connect the 3PDT to this switch instead of to the rate-LED. Gilette wrote:

I see what you mean by adding a remote switch. Since you're building a true bypass stomp box you don't need one, right? Or is there something I'm missing? |

Thanks for the replies Frank and Björn! One minor thingy is the kinda high tremolo speed/rate at even the (s)lowest setting. Is there a simple mod to lower the slowest rate? Simple as in: not having to solder anything to the smd components. My other guess is that it'll need to be a quite big resistor to make enough of a difference and that it would probably reduce the max speed to what is currently the lowest speed, so, I'll have to put it on a switch. For the same reason I guess a larger value pot wouldn't be convenient as it would probably give a range of very slow rates between 0 and 8 and then have the usual speed range in the last tiny part of the turn.

Yes, you are right. Its not easy to change the lowest setting without changing the tuning of the oscillator. The easiest way is probably to try a 220k or 250k pot. Preferable anti-log type. |

So, I did some experiments. Lowest speed is 210 bpm (3,5 Hz) The lowest speed I was aiming for is around 180 bpm. 0k extra : 210 bpm Your guess/suggestion for a 250k pot was spot on. But I'm afraid that too much of the dial will give me slow speeds and only a fraction will be the more usual speeds. I also fed the SurfyTrem a 110 Hz signal and hooked it up to audacity, which gave some very interesting finds: The screenshot below, shows it's a genuine sine wave tremolo! All too often tremolo pedals list sine and square as modes but in reality they offer triangle and square. In the screenshot below I have the speed at minimum (210 bpm) and I'm turning the intensity from 0 to 10. The screenshot below is zooming in on speed:0, intensity:10 which clearly shows the on/off cycle In the next screenshot I have the speed at maximum (540 bpm) and I'm turning the intensity from 0 to 10. The screenshot below is zooming in on speed:10, intensity:10 In the next screenshot I have the speed below the stock minimum by using the extra speed pot (it's around 175 bpm) and I'm turning the intensity from 0 to 10. Conclusion: it's an awesome tremolo and great companion for the SurfyBear! I also really like the fact that you priced the DIY kits so low, this way they're within everyone's reach. Thanks for two great circuits Björn! Last edited: Jul 26, 2017 19:01:33 |

Is there a reasonable resistor to add in series if one would add a "slow" / "fast" range switch? |

Anything over 100k will also mean that the maximum speed in the 'slow range' will be lower than the stock 210bpm slowest speed in the 'fast range' To go slower and slower you need exponentially/logarithmically larger resistors. And the lower you want the lowest speed, the narrower the slow range will be. Last edited: Jul 31, 2017 17:02:48 |
