In another thread Greg (Lunch Money) linked to a place called guitarheads for inexpensive pickups...the site itself is kinda lame, but they sold this little beauty. The QDD2, an onboard guitar pre-amp with a twist, instead of a toggle switch it uses a 5 position rotary switch.

In two other guitars I have the EMG PA2

Image

as I love pre-amps the QDD2 really peaked my interest, I chose to install it in the Daion I bought from Muff Wiggler (one more chance to show it off :hihi:). It replaced the lower left tone control with no modifications needed.

Image

right away you can see how more there is to the QDD2 than the PA2...both have trim tabs and on both I keep them low...also there is not a PA2 on the Daion, I'm just using it for comparison.

Installation was a snap and I was playing in minutes, I wont be posting soundclips, sorry that's just too time consuming. I tried it with several models in my POD xt I'm using on some songs now. The by-pass is true with no difference detected and the clean boost is very good. Back in the stone ages I had a toggle switch type pre that was made by a company called audiocraft, it was a three position with a similar boost to the clean boost here and a boost adjustable to 18db. I loved that pre as it gave me two vastly different drives as well as a bypass, sadly I had to give up the small boost with the PA2.

The Blues overdrive position on the DD2 is about perfect for me to use after the clean boost, it's a great warm tone with power. Both it and the clean boost really improved the "singing" on bends, something my warmoth does well.

The rock distortion is pretty much like a Rat, kinda fuzzy but not to fuzzy. The metal is scooped and pretty good if I need to cut up some firewood while playing.

The unit itself is about as noisy as the PA2, not bad but the expected noise is there. Of course it's easy to deal with that these days.

The Daion has coil taps for both pick-ups so I can split either one to single coils. Obviously with 4 choices of drive plus no drive at all, the splits and the typical three way pick-up switch the amount of possible combinations is awesome. Naturally I found that the pick-ups wont wimp out now when played low and with pre-amp choices combined with the splits I could go from a strat sound to a paul sound with emgs (think zakke) to a paul with soapbars. I was able to get some of those bright tones you might expect from a jaguar as well which was cool.

I'm gonna spend weeks exploring the myriad of tones this beast creates, it certainly is worth the price tag of 27.99usd. I wonder how many more I might own before the end of the year. If you're looking for something useful, inexpensive and fun to add to your guitar this might be worth a look. Also I ordered it Friday and it arrived today...:tu:

Tempting... I'm just wondering how much more metal I can make my sound. :D
Remember the iLokalypse Summer 2013

Samples and presets and free stuff!

Sounds good Hink, I like the idea of a 5 position rotary switch :tu: but it's way beyond my meagre soldering skills I'm afraid.

Guitar Fetish do similar stuff, tho' they are more expensive http://store.guitarfetish.com/activepreamps.html

cool link Ian...I gotta say though, you're wrong about soldering. If you can solder a pick-up you can do this. All you do is interupt the final output lead and solder it to the input and a lead to the jack from the output. You need to put a stereo jack in and you just have to run a lead from the the sleeve connection on the jack for ground (along with the ground from your original jack) to the ground terminal on the pre. That leaves one terminal empty on the jack (ring) and one on the pre. The red wire from the battery clip goes to the pre and the black goes to the ring terminal on the jack...done.

BTW reading my post above it sounds like I'm saying it's noisy, but it isn't really...:)

I was lost immediately after the word soldering Hink :oops: :hihi:

it really isn't hard, but describing it was :hihi:...I did some more tests, I turned the trim up about 1/3 of the way. I didn't really like it so I'm probably setting it now at 10-15%, when I turned it up it did start with the hiss and it started to feedback some on the three higher settings...which is good to an extent, just not that much gain for me. For gain heads this is great..:tu:

I did make 5 basic clips to compare in the spectrum analyzer and I gained some insight to what it does...a couple settings boost the low mids/mids and boost the highs about 3.5k up to about 8k. The metal settings scoops the mids while pumping the low mids and high mids a bit and pumps up the highs.

Cool that it's giving you some tonal variety, Hink! And for cheap, too. I'll have to keep them in mind for future hotrodding.

it would be nice to have an addtional toggle installed to kick it in for leads and such...

I just had gobs of fun with this and my little fender blues jr (which goes up to 12 btw :hihi:). There's some really ear pleasing tones mixed in there, it was inspiring all kind of ideas with the bridge pick-up on single coil and rolled back to under 50%, the neck on HB at a little over 50%, the master tone open and the pre on the third position :love:

well it's close to two months since I got this gem...my feelings havn't changed. Lately all I have been playing is this guitar...for the short money this thing costs you get plenty of bang for your buck :)
