Pedals: same design – different circuit

Platine There are some pedals that have been put on the market a long time ago and that, because of their sound are known as the legendary ones.
But sometimes the circuit has been changed over time. Now and then these changes were only little and became necessary because several parts were not available anymore. But sometimes parts of the circuit have been transformed without this being externally recognizable by a new or changed design.
Here I would like to introduce a few of these pedals.

Boss DD-3 and CE-5

A pretty good example for a change of wiring is the Boss DD-3.
The first DD-3 pedals had the same circuit like the previous version, the DD-2 and were also based on a big chip like the one that has been used in some rack delays of the 80s.
Someday the wiring has been changed completely – the design of the enclosure and the name remained, however, the same.

It was similar to the CE-5 chorus.
The first CE-5 pedals used an analog circuit. The current CE-5 is a digital chorus in the enclosure of the primary CE-5.

Rockett Archer

The development of the Rockett Archer is also quite interesting.
In collaboration with Bill Finegan, the manufacturer Rockett produced the Klon version KTR.
Based on this knowledge, the Archer has been brought on the market. It is based on the wiring of the Klon with a germanium diode overdrive.
In cooperation with the ProGuitarShop the Rockett Archer Ikon has been produced – with germanium diodes in the circuit, just like in the first Rockett Archer.
The Rockett Archer itself has since been equipped with silicon diodes.
So if you want to make a Rockett Archer sound like the Ikon you only have to change the silicon diodes by germanium diodes.

Electro Harmonix Deluxe Memory Man Tap Tempo 1100

For a short time EHX produced the Deluxe Memory Man Tap Tempo 1100 with the old, original Panasonic MN3005 chip.
These chips have a legendary reputation but unfortunately they are not produced anymore.
The first Deluxe Memory Man Tap Tempo 1100 were sold out quickly. And the actual versions are produced with a XVive 3005 reissue chip.
At least the two versions of the TT 1100 can be differentiated by their color: the recent one has a darker blue on the left side.

Way Huge Supa Puss

When the Way Huge Supa Puss was put on the market it had, unfortunately, some little weaknesses according to its adjustment. Using the modulation pot, for example led to some kind of oscillation.
The first pedals has been reworked for free and a changed version appeared on the market.
Although this one worked fine now, more and more users complained about the divergent sound.
Whether this is a consequence of the changed circuit or the altered tuning of the trim pot, still is unclear.
