Lifer Posted February 12, 2013 Share Posted February 12, 2013 Been experimenting with reamping recently and really like my tone with: Clean - Catalinbread SFT - Ashdown Hyperdrive running parallel. I've had a look at the blending pedals like the Badger Schism but they seem quite expensive. If I can make a pedalboard that protects it what are the potential pitfalls of using a mini mixer like [url="http://hq.pingdynasty.com/blog/2011/03/29/modded-soundlab-mixer/"]http://hq.pingdynasty.com/blog/2011/03/29/modded-soundlab-mixer/[/url] to blend the signal? Any recomendations for micro mixers appreciated! Quote Link to comment Share on other sites More sharing options...
cheddatom Posted February 13, 2013 Share Posted February 13, 2013 how are you going to split the signal before it gets to the pedals? I'd just go with an LS-2 Quote Link to comment Share on other sites More sharing options...
Lifer Posted February 13, 2013 Author Share Posted February 13, 2013 I'm want to combine 3 signals; clean, OD1 and OD2 rather than switch between loops... Quote Link to comment Share on other sites More sharing options...

[/quote] With the LS-2 you can combine clean and something else (OD1 or OD2), but not all three separately... so no good in this case. Two LS-2???

Lifer Posted February 14, 2013 Author Share Posted February 14, 2013 Having investigated I think the best way will be something like the Badger or Wounded Paw, gonna be a lot less hassle. Quote Link to comment Share on other sites More sharing options...
xgsjx Posted February 14, 2013 Share Posted February 14, 2013 Make a mixer pedal. It's not hard. I made this loop & mix pedal... If you want the schematics, let me know. Quote Link to comment Share on other sites More sharing options...
Lifer Posted February 14, 2013 Author Share Posted February 14, 2013 Can you do schematic for Clean + 1 + 2 blender? I can solder but the theory behind it all escapes me... Cheers! Quote Link to comment Share on other sites More sharing options...

paul_5 Posted February 14, 2013 Share Posted February 14, 2013 4 channel mixer with a handful of components: http://tagboardeffects.blogspot.co.uk/search/label/Mixer You could sub a TL072 with an NE5532 if you were [i]really[/i] fussy, but the 72 is a very clean sounding chip.

Input 3 + 4 phase reversed and then all three (original dry/SFT/Ashdown) combined on an external bus channel which outputs to the master 1 + 2.

xgsjx Posted February 14, 2013 Share Posted February 14, 2013 I used this to make a 2 channel mixer on my pedal. You can add or remove a channel to suit. Splitting the audio is a simple case of taking 3 jack sockets & wiring it from 1 to 2 (no buffering needed). I can't find a schematic, but I can sketch you one late if you need it. Here's a handy web...

tonyquipment Posted March 17, 2013 Share Posted March 17, 2013 Yeah the micro mixer in lieu of a loop line selector pedal works great! I have a soundlab mixer on my board ! Quote Link to comment Share on other sites More sharing options...
dannybuoy Posted March 29, 2013 Share Posted March 29, 2013 You don't need a mixer to blend 3 signals (SFT + Ashdown + clean) since the Ashdown already has a clean blend. I'd just use an LS-2, then if you need more clean volume just turn down the blend and increase the volume on the Ashdown. But I'm gonna throw a spanner in the works now - the SFT inverts the phase so you'd end up with a volume drop and strange sound when mixed evenly since the two signals cancel each other out. To remedy this you can put another cheap pedal that inverts the phase again, such as the EHX LPB-1 next to the SFT, or you could use something like the Wounded Paw Super Blender which has phase switches.

Jazz Ad Posted April 2, 2013 Share Posted April 2, 2013 (edited) A simpler and cheaper solution would be to use a patch cable with inverted phase. Edited April 2, 2013 by Jazz Ad Quote Link to comment Share on other sites More sharing options...

Jazz Ad Posted April 3, 2013 Share Posted April 3, 2013 No such things in alternative current. It is exactly what phase inversion switches do. Quote Link to comment Share on other sites More sharing options...
elephantgrey Posted April 3, 2013 Share Posted April 3, 2013 changing the phase is how out of sync the wave is to the original (a phaser does this just to varying amounts set to an oscillator) what the poroblem here is that the phase has been inverted by 180 degrees, that that needs to be inverted. here is an example of different degrees of phase: What changing the wires over on the lead does is create a [url="http://en.wikipedia.org/wiki/Ground_loop_(electricity)"]ground loop[/url], this can lead to noise issues. If you've ever had a active DI, this is what the ground lift tries to avoid. Quote Link to comment Share on other sites More sharing options...
