At left, a Dan Armstrong Green Ringer made by Wareham. As Craig Buzzart described, notice
how it features considerably more interlocking tabs on its outer casing, which makes the units more sturdy when
stacked. Many such features were cut back when it came time for Musitronics to produce their version
as can be seen above right. Notice the larger, (and fewer) tabs as well as what appears to be a more economical output
jack. According to Craig, the Wareham units also had more 'heft' to them and were built with better materials overall.
However, it must be remembered that Musitronics got both Dan & George 'on-board' with them to help offset the cost of
their already expensive MutTron effects units. When it came time for them to produce the Dan Armstrong
effects units, there was little funding available and they produced them with what they had. Despite the lack of the
higher quality components found in the Wareham units, many of the Dan Armstrong/Musitronics units have since become
collectable to musicians.
As can be seen at upper left, the Dan Armstrong effects units manufactured by Musitronics feature their Logo
on the front, which is probably more commonly recognized from their MuTron pedals and effects. Internally the
Musitronics name can be seen at the top of the circuit board when it's removed from the casing as can be seen
in the upper right.
As seen at the upper left, one unique feature of all Dan Armstrong effects units is the ability to use the
unit plugged directly into an instrument, or.... alternatively, it could be plugged into an amplifier. The
instructions for this change were clearly labeled on the outer casing.
At upper right, and with the cover removed one can see the aforementioned yellow 'plug' wire and blue 'jack' wires - both highlighted
here with arrows. By unsoldering these two wires, and exchanging them, one can easily choose where the unit is to be
stationed at. Dan went on to add that "there were plans at Musitronics to eventually offer the effects devices in floor stomp
box models but they just never got made. Once they were into production it was too easy to just let it continue in its
present form. No one seemed to bother following through with it after that."
As seen at left, the inside of the Musitronics unit is compartmentalized. A single 9 volt battery rests in place just
underneath the ¼" female guitar jack and mini toggle switch. It is kept separate from
the circuit board via a non-conductive fiberboard material, with only enough room to allow the wires to cross under
this barrier. Notice the foam rubber material on the cover just underneath the ¼" male guitar plug - strategically
placed to keep the battery from moving once the cover is secured back down. However, some players still get nervous
above having the battery's metal casing so close to the wiring above and put a strip or two of black electrical tape
around the 9v battery.
At upper right, again the Musitronics name can be seen on this Purple Peaker unit, but the letters are smaller on this
circuit board than on the one seen above, from my Blue Clipper, which is an older unit.
At upper left the two circuit boards can be seen in a side by side comparison. At the left is the circuit board from my
Purple Peaker, sporting smaller letters to make up the Musitronics name, while at right the circuit board from my Blue
Clipper features larger letters to make up the name. The Danelectro battery that came with my Peaker unit seems
somewhat appropriate. Battery life on these units seem rather lengthy, which would seem to suggest that these units
consume very little power.
As can be seen above right, the Dan Armstrong effects units were packaged in a white cardboard box with Dan's name on it, as
well as Musitronics, and their logo. Folded and coiled up inside the box is an instruction sheet depicting how to
change the battery, as well as once again covering how to convert the unit for use at an amplifier input. It then goes
on to advertize by describing the other effects units in the series. Lastly, the one year warranty is listed. This
instruction sheet can be seen in the brochures section.
