Hey George, all healed up I hope MJMP's suggestion of using the headphone out is worth a try (turn the HF vol down though) as then there is no return (I'm assuming you plug your guitar into the tuner and tuner out to MP1??). The downside of coming off the HF out is the signal is whatever patch you've selected and distorted tubes add lots of harmonics (why we like them ) which can upset some tuners making it hard to find the note (e.g. my IPS33 harmoniser has a distortion loop so it can get the signal straight from the guitar to "track" better).
You could also just plug into the tuner to tune and then plug into MP1 when your done (not go through the tuner thus not add hum)
Or better still, buy a Peterson Stroboclip see previous post, it's so much more accurate and no hum (no cables, clips on), best tuner I ever bought and I can tune my acoustics as well.
Cheers R
hey mate getting there.. work isnt helping!! rather be home playing with rack gear.
no im not going into the tuner and then out .. its out of the signal chain. so just using an output. The soldano pre doesnt have a second form of output so all i can do is use the second dry output of the rack wah to the tuner.
saying that if i use the send on the ada mp1 i still get the bad ground loop.
saying THAT! i tried marshalljmps suggestion to use the headphones from the ada mp1 and this seemed to do the trick perfectly!!
however i would have liked to come out of dry output on the rack wah to facilitate any preamp. I simply cannot make up my mind between the sp77 and the ada mp1.. ill play through one and just fall in love then 10mins later ill plug into the other and fall in love with that. though i will admit.. hence why im on this forum .. is that the ada mp1 is very versatile in comparison though the sp77 has this edge over the mp1 though a 1 trick pony essentially haha.
all good .. im learning about it all. and will play around somemore with other combinations. Im pretty happy with the tuner and i like the big display and i can just turn around and look at it.
i appreciate both of your inputs and discussions and helping me !! cant believe i fixed the sp77 myself and learning heaps about racks in the process.
there will be more questions to come and im enjoying this journey.. the best thing of all is at home running in stereo between 2 quad boxes .. theres simply no other sound like it!! love it!! shame its not practical for live situations hahaha running a quad in stereo isnt the same with the speakers next to each other hehehe
