Questions about pedals

1) Are T.Miranda pedals clones?

No, if you are looking for clones look elsewhere.

2) Are T. Miranda pedals compliant with Rohs and WEEE directives?

In accordance with directives imposed by WEEE (Waste Electrical and Electronic Equipment) and Rohs (Restriction of Hazardous Substances), intending to ban from the markets non-recyclable substances in manufactured products, lead alloys and other substances that are hazaodous to human health and the environment.
We, at T. Miranda, only use components from manufacturers that are credentialed by official institutes and laboratories (UL) complient with WEEE and Rohs norms and regulations (those include Solder "alloy Sn3,9Ag0,6Cu", capacitors Pb free and RoHS compliant, resistores , trimmers, trimpots,  integrated circuits, switches, diodes, potentiometers).

Below are the maximum concentration of substances in electronic components:

*Cadmium < 100 ppm
*Plomb < 1000 ppm
*Mercure < 1000ppm
*Chrome  6 (hexavalent) < 1000 ppm
*Polybrominated biphenyls , Polybrominated  diphenyl ethers: retardateurs de flamme brom├ęs
*PBB + PBDE < 1000 ppm

T. Miranda products use the following components from selected manufacturers:

Resistors (metal film), polyester and tantalum capacitors, 16mm potentiometers, Sn3,9Ag0,6Cu alloy solder, low temperature melting point at the
3pdt terminals (5-8 year lifespan),  2.1mm Dc jack, Switchcraft Jacks 111; Jrc4558dd/mn3007/sad512/sad1024  IC's,
1,5mm thick steel enclosures (nearly perfect isolation from intefearence and noise),

3) What is T. Miranda's amps and pedals manufacturing process?

All T. Miranda products are crafted and tested by hand, one at a time.

4) What is custom?

Custom means equipment made for an individual' s nees. Usually with higher quality components, point-to-point amps, etc.

5) What is true-bypass

We all know that racks, cables, pedals, etc, suck the tone of our instruments befor it reaches the amplifier. True bypass means that the signal reaches your
amplifier without changing the signal or the pickups impedance before it reaches the amp. Many racks and pedals use buffers which drasticaly changes the
impedance of the guitar signal.

6) What' s the difference between buffered-bypass, hard-bypass, and true-bypass?
a) buffered are used in pedals like boss, ibanez, sansamp, dunlop, etc. The guitar signal goes through
an active parallel circuit even in bypass.
b) Hard-bypass are used in many Marshalls, Jim Dunlop (Crybaby), MXRs,
Electro-Harmonixs. In this system even though there is a direct hard connection between IN and OUT in bypass,
the circuit is still conected to the bypassed signal, causing tone degradation.
c) In true-bypass, the signal is completely isolated from the effect's signal, so you can use several effects
in series and have nearly no tone degradation. It is as if you were plugged directly to the amp.

7) What about Bob Bradshaws switching system?
This system is used to bypass pedals completely and is usefull for guitarrists who want several effects turned on/off with a single move. Individual effects do not need
this system to avoid signal losses when in bypass.
