ok so if VB is bias how is the bias obtained how do you have a 9v source and a 4.5v source?>

hello all,

i have a question concerning my build but can also shed light on other future projects. im bulding the Rothwell Love Squeeze compressor pedal from a popular vero layout found at sabrotone.com. i have all the components to build but am currently at a stand still with the voltages required. obviously 9v, but im also looking at the schematic of the Love Squeeze and there is VA and VB also listed in the circuit. what are they representing and what are the voltages of them? i could be making this harder than it is but its what is holding up my progress at this point.

any input is appreciated!

Cameron

hello,

i too am looking to mod this pedal but im sitting at my breadboard with an incomplete circuit information. first of all what is VA and VB in the circuit? and what do they represent? i understand that they are voltage sources but what are the voltages? im looking to implement 3 of the 4 mods listed in this post but before i can proceed i need to get the love squeeze working pre mods lol. any help would be a godsend at this moment.

I'm a big fan of linear over log for volume knobs. Any time I see log being called for I automatically sub in a linear pot instead. When I notice unity gain then sits around 12:00 I know I made the right choice. If it then sits around 9:00 or 10:00 only then do I sub it for a log pot. Which is usually almost never the case. I have a Love Squeeze pedal and I was foolish enough to use a log pot for volume. I hate the spread of it, I still have to get around to putting a linear pot in there instead.

Awesome! looking at the sabrotone website where i found my vero layout for the love squeeze, there are about 8 comments from various people that have built the compressor but no one states what kind of pots should be used. i feel like i understand it much better now, and i can see where a linear pot for a volume control makes sense. im gonna have to agree with midwayfair too about breadboarding the design. i just have to buy the components before i can move forward. and I dont want to buy the wrong components and end up SOL for my project. (building this for a final in college) thanks for all the help!

ok i think i understand, because of the "taper line" of a linear pot is straight kind of like a 1:1 ratio increase vs an audio pot you get more detailed control because the ratio represents something more like 5:1 ratio increase followed by a 1:2 ratio after the threshold is passed. creating a concave curve? after the pot "opens up" it exponentially increases requiring less of turn on the dial to fine tune it?

hello all,

this is in regards to my love squeeze clone build, but i also feel its vague enough to shed light on why we would choose B10K pots over A10K pots and vice versa. I was under the assumption that i was supposed to use B10K (linear) pots. but recently i was pointed towards the "Rotten Comp" PCB which is modeled after the love squeeze.

PCB and BOM for the Rotten Comp by GCFX:

this is the first time ive seen real directions for A10K (audio) pots being used for the build. why audio pots? wouldnt you want your controls from 0-10 on the knob? im questioning my understanding of the difference between these 2 choices. please help?

Hello All,

I'm in fact a newbie at this whole pedal building game, but i also wanted to post here too.  I'm currently a student at the Art Institute of Seattle undergoing their Audio Design program. This quarter I'm in a semi-advanced electronics class, and my final project is to build a pedal clone. I've chosen the Rothwell Love Squeeze (Info on this pedal found under link 1). I'm building it from a layout posted on sabrotone.com (link 2), and I wanted to MOD this pedal using the advice from one of MadBean's very own Midwayfair (link 3).

in the madbeanpedal forum post Midwayfair said to vary R10 with a 10K pot (assuming linear) for a threshold control. Also vary R9 with a 10K pot for an attack control (also assuming linear, but confused on what is actually happening). Does R9 (22R) keep the attack at almost immediate, or does varying the resistance up to 10K make the attack almost immediate? Midwayfair also said to vary R11, the decay resistor, with a 100K pot for a full second of decay.

my biggest questions are, if i go ahead and MOD in a threshold control, attack control, and decay control will the pedal still maintain its balance and perform as expected? Because of the design of my enclosure, i would like to make R11 (Decay control) a 100K trimpot mounted on the inside of the enclosure or on the strip board itself, as a kind of "variable set and forget" control. leaving me with my main VOLUME, THRESHOLD, COMPRESSION, and ATTACK on the front of my enclosure. because i havnt purchased anything yet i cant tell you if this will work, but i would like advice to see if my theory is sound, or perhaps input to make it the way i would like? the end goal is to make this idea a reality so there is a deadline.

P.S.

I have a KILLER design picked out for this project and i would be more than happy to post pictures of the final product so the people that helped me can see what i did with their knowledge.

Respectfully,
