So... how about difference in opamps? I'm using TL072.
I attach a frequency response graph I've taken from another cabsim (in the past). Four different opamps.

Re: BAJA CV30M1960A Speaker Simulator pedal
bajaman - can you test your real circuit with rmaa? I've just finished re-breadbaording and measuring the sim. Same story.. strong 5kHz peaks. As for the plot difference between film and mlc caps. It may be caused by different capacitance values. Film caps - 1uF, mlc around 930nF (tested with cheap ...

Re: BAJA CV30M1960A Speaker Simulator pedal
I'll recheck values and redo the breadboard layout. Check the recording on souncloud. That's all I was able to record today, nothing fancy.
No cab, then four times BAJA CV30M1960A, then cab IR two times.

Re: BAJA CV30M1960A Speaker Simulator pedal
No sound samples yet. As for now I can post frequency response graph. There are four plots. With number 1 - 1uF multilayer ceramic capacitors, with number 2 - 1uF multilayer polyester capacitors (dipped type, MKT).

Re: BAJA CV30M1960A Speaker Simulator pedal
I have it on a breadboard now, working. I'll try to capture some riffs later.

Re: BAJA CV30M1960A Speaker Simulator pedal
Any chance for switchable mic positions? Something like center, cone, edge.

Matnya on a PCB, board mounted pots. I added a switch that lowers amplification of the first opamp.

Re: Matnya [documentation]
Short sound sample, as promised. It's a Killswitch Engage Rose of Sharyn DI track played through Matnya. Recording came out a bit bassy so perhaps I should EQ some low frq from guitars. Recorded in Reaper. Mesa cab IR applied for each guitar track. In order of apperance - first there is a backing tr...

Re: Matnya [documentation]
I breadboarded this circuit yesterday. I am very pleased with a sound. Tons of gain. Even with a potentiometer set to zero there is still great amount of gain. A little bit bassy as for me so I lowered value of C6. Sound sample soon.

Re: Diezel VH4 Pedal [schematic]
Since i'm interested in building this and it'll be my first pedal, should i buy the UK-electronic or can i save some by buying all the parts myself? Hard to say.. it depends on where you buy the parts, from how many suppliers, etc. Might be easier and cheaper to buy a kit. btw - not the easiest sub...

Re: cabsims... and even more cabsims
Heh.. tough question. I'd list three or four cabsims I liked most. LS14, Lart (the one from my second batch of cabsims, not the simple cabsim), 4x12 Celestion Vintage 30 (TrueVAL), I also like multicab speaker sim by DSM (because of possible adjustments). Someone on the Russian forum mentioned about...

Re: cabsims... and even more cabsims
Did your KMG V30 cab sim have a issue of being below unity volume? My build is slightly lower then unity volume, and I would love to get it up (volume that is). I tried increasing the voltage to 18vdc and 32vdc, but this had no improvements on volume. Sorry, cannot help you with this. I've breadbor...

Exactly.. we need a new DI trackOptical wrote: Good work. Did you have any tone stack after the circuit?
Lasse really needs to sort us all a new DI track
Each preamp had a tone stack. I'm not sure which one I used in UBS (probably the one from MDR or ENG).

Re: BAJA MDR overdrive pedal 9v 060218 [documentation]
Please note - there is a speaker cabinet impulse response added to each track (Engl 4x12 loaded with V30 speakers). Your setup may sound a bit different.marcao_cfh wrote:Thanks a lot for this clip! I decided to go first with the UBS thanks to your demo.

Re: BAJA MDR overdrive pedal 9v 060218 [documentation]
So far I've breadboarded UBS, MDR, EVH and ENG. I like them all Had some oscillation issues with ENG.
SLO and VH4 next in line. Here's a short recording of a DI track played through each preamp:
