My Puck'n Stompa moves when I play it.
If you find your puckn stompa slips around while you play it, and you don't want to buy a Megastomp stand, then here is a trick! Don't use up a roll of Gaffa tape trying to stick it to the floor, but in stead get yourself a little carpet square, like a mat or a carpet tile (loop pile preferably). Also get some Velcro "the Hook side" it comes in coins and strips and it does'nt matter which you use. Stick two velcro bits together so you end up with a strip or coin that has the hook on both sides! Stick this down onto your carpet, it will hook on nice and firm, then place your puck on-top. Now its going nowhere! and you can easily just tear it off, when you want to!
Will the Blue-Tack mark my guitar?
The blue tack it self will not mark your guitar, however if you leave it permanently in one possition the area under the pickup will fade differently to the rest of the guitar. So alwaus ensure to move the pickup every few weeks/months depending on how new/ old your guitar (new guitars fade quicker) is and if its in the sun or packed away!
I am having Feedback problems with the peterman piezo guitar pickup when I use my Acoustic Amp.
This is often caused by the Amp input being too Hot for the already Very Hot Peterman pickups...The input signal is too loud and will cause a High frequency distortion and feedback.
This is easily fixed with an attenuator. No Preamp is required as the signal is TOOOOO LOUD.
More On Feedback:
Feedback is caused by the sound from the amp being directed back towards your instrument and this vibration again being amplified until you get a Howling sound called “Feedback”
The nature of the peterman piezo pickup is to make the guitar part of the pickup, when un attached to the guitar the pickup makes no sound, unlike Vocal microphones the piezo bug needs to be attached to the sound board, turning the guitar into part of the microphone. These pickups sound extremely natural but can give feedback. However like anything this feedback effect can be reduced and sometimes overcome completely.
Feedback is usually around the Midrange frequencies and sometimes in the bass and treble. Treble feedback is very directional and can easily be avoided by moving away slightly or simply facing away from the sound source (speaker). This can also be effective for midrange feedback. Firstly it is important to note that most guitar amplifiers are very midrange focused and a lot of them have open backs, this is a real problem for this kind of pickup. The best amplifiers are those with closed backs and a very flat frequency response. Like a Keyboard amp or a PA.
Most Acoustic guitar amps are OK but they still suffer from a false midrange. Sometimes this is done to compensate for the popular Bridge/Under saddle pickups that sound normally very cold and lack the warm mid tones. Amp designers then “add” warmth to make their amps sound “better” but this can work against you with a contact pickup that doesn't need any extra warmth.
So What to do?????
The solution is multi fold,
Try not to sit infront of your amp, it is nice to hear your own guitar but it is more important for the listener to get the full sound (especially if you are paid for the gig).
Sit behind the amp where possible. You can even try a little sound screen like used in Recording studios between you and the amp. If you need to hear yourself try a small foldback speaker at ear level or maybe an earphone.
If your amp is an open back amp, you can put something in the back of the amp, like a pillow or similar reducing the sound escaping through the back.
If possible try different amps, especially NOT electric guitar amps.... Place the pickups as close to the bridge as possible, Play harder and louder so you wont have to turn up the amp as much.
DO NOT USE COMPRESSION or use it very carefully.
You can adjust out the problem frequencies with an Equaliser.
Try a Feedback destroyer, this is a rubber plug you place in the soundhole. Or sometimes an electronic device that focuses in on feedback and attempts to stop it.
Some players fill their guitar with old “T” shirts or similar to reduce feedback.
Experiment with different positions of the pickups, sometimes there is more volume and less feedback from an unexpected place.
Try tuning the pickup to a higher frequency, by turning the tuning screw slightly tighter.
If you are using a specific Acoustic Guitar amp, try different inputs. These pickups work well in Line inputs (not XLR) as well as HiZ, the HiZ input is designed for ultra high impedance piezo pickups and can sometimes be too “hot” for the peterman pickup making it too loud at the input stage causing unwanted natural compression that will cause feedback.
Do not use Distortion effects or effects that compress and limit the sound, this will force the low notes loud and cause bad distortion and feedback.
Run your line in trim fairly low and turn up your master, even though it looks like the signal is within the range of the preamp, run it slightly under. You knw the old trick of turning it up until the little red lamp comes on, and then taking it back a little....... Well take it back a little more!!
Make sure that your pickups are mounted securely, and that they are not too loose. Also make sure that they are in contact in the centre only, if the whole pickup is in contact with the sound board you will loose volume and you will need to turn up your amp, causing more feedback.
If you have found other solutions , let me know and I will include them in future list.
Good luck Peter Sesselmann
