Frequently Asked Questions

As per the original, there are 4 phasing stages.

Yes - the Flying Pan originally had 4 trimpots that were factory-calibrated, and three of these are 'exposed' on the 777 when the base of the pedal is removed to allow more adventurous users to experiment with different settings. One trimpot is for adjusting the centre of the phase sweep, whilst the other two are for adjusting the depth of the tremolo effect on the left and right channels. No damage can be caused by making these adjustments, even at each extreme, and a default calibration setting is marked clearly so you can return your unit to 'as-built specification' if you wish.

We will work with you during the development phase of your custom project to make sure it is exactly what you want, however to be clear - there is no returns of custom designs or of 'stock' pedals with modifications you have ordered. The sole exception to this is where is allowed for under EU regulations covering 'fitness of purpose'. More positively - while PSS is a business, our goal is to make cool stuff that helps people create good music. We regularly turn away customers that we think could be better helped somewhere else, or if there is something already existing on the market that might better suit them. Because of this 'sales' policy, we can almost 100% guarantee you will be very happy with what we make for you.

Unfortunately it's not practical to stock the appropriate AC power supply for each country, and even if this was possible then shipping the power supply with the pedal would add significantly to the cost because of the extra weight. You will need to source your own power supply if you purchase either of these pedals.

You can use either an expression pedal OR a volume pedal - with the volume pedal, simply connect a 1/4" cable between the 'output' and the socket on the infinitphase. Note that when using the speed control in this manner, the 'rate' control on the infinitphase determines the maximum rate, and then the pedal is used to 'slow down' the LFO pedal from this maximum rate.

The best way to experiment with the phase sequence controls is to set the LFO to a triangle shape (LEDs panning back and forth), symmetry at 12 o'clock, rate slowish (around 9 o'clock) then turn the 'range' control down until only 3 LEDs are being illuminated in time with the LFO shape. Then you can play with the phase sequence controls and more easily notice they affect he sound. Or better still, turn the 'range' control right down until only one LED is illuminated (the middle one of the nine) then adjust that control only. NOTE - it is very important to realise that the far-right phase sequence control ALSO controls the sound in the step-phase mode, so make sure that you experiment with that one too.

An expression pedal with an internal linear 10k pot is recommended, some examples of which are:

• Dunlop DV3 volume / expression pedal
• Boss EV5/EV7 expression pedal

Unfortunately it's not practical to stock the appropriate AC power supply for each country, and even if this was possible then shipping the power supply with the pedal would add significantly to the cost because of the extra weight. You will need to source your own power supply if you purchase either of these pedals.

We believe that the Pi-Phase mk2 is as close a reproduction of the original pedal as it's possible to achieve in the modern day. By reference to the original schematics, and with knowledge draw from ownership and use of two Bi-Phases (and a Mu-Tron Phasor II), it was possible to design a more compact version of the original. It was decided to incorporate the foot-switching directly into the pedal itself so the Pi-Phase mk2 would be usable on it's own with no need for external devices / pedal-pedal switches.
The Pi-Phase mk2, like the original, features all-analog LFOs and audio sections, and through-hole components for the critical parts (the LED and LDR coupling section). 1% tolerance metal film resistors were used instead of the original carbon types so as to reduce noise. The +/-15V internal power supply design was retained, as this is a big part of the high-headroom / clean sound.
A great deal of experimentation was done with the optical phasing section, so as to match as closely as possible the response and sound of the original pedal. Anecdotal comments from users of the Pi-phase mk2 comparing their pedal to an original Bi-Phase range from '95% of the way there' to 'identical in sound and function'. Allowing for sentimentality and considering the price and availability of the Pi-Phase mk2, this is a result we are pleased with.

Yes - in fact there are 10 trim-pots that allow various parameters to be adjusted. However, it is highly recommended that you don't go adjusting these trim-pots without guidance! Doing so without knowing what you are doing can mess with the calibration of your pedal.

The Piphase mk2 requires a 16VAC (that's AC, *not* DC!) power supply with a 2.1mm barrel plug connector. We recommend the Peavey 16.5VAC / 1100ma power supply, Peavey part number 70900660, or the current item is here.

Please be sure to use the correct AC power supply with your Piphase mk2, as connecting the incorrect power supply will damage your pedal and void your warranty!

Although we might sometimes make donations to our musical friends or to worthy causes, Prophecysound does not offer free or discounted pedals in exchange for an endorsement. The best 'endorsement' of our products is that working musicians are willing to spend their hard-earned money on them.

No - if we do this then the pedal can't be insured to it's full value, and we only ship fully-insured / registered. Also, tax agents these days can simply do a web search to check the 'real' value of anything being imported. You need to be aware of extra duties imposed by your government / area when importing pedals from us, and make sure you can cover the extra expense. Please note - you cannot refuse delivery / return a pedal upon discovering an unexpected extra charge for import duty.
