The Quick Questions Thread!

This thread is meant to be a resource for anyone with a short, (hopefully) quickly answered question that perhaps doesn't need its own thread. We've only got a few rules, and they're more like guidelines:
  • This thread is staffed by members of the Who To Listen To list, a group of forum regulars who are elected at intervals by popular nomination and existing member vote. The list can be found here: WTLT List and Chat Thread
  • Great quick questions are ones that can be answered objectively or at least do not have a controversial aspect. Subjective questions or questions requiring some back-and-forth conversation deserve their own threads!
  • We're going to aim for a "one question, one answer" format. If your question is going to need followup, make a thread. Similarly, if a question has already been answered, please try not to elaborate or confound the issue by answering it again unless it's really necessary.
  • Try to give all the information we might need to answer the question in your post. If we have to follow up to clarify or ask more questions, it slows the process down. A quick question doesn't have to mean a short post.
  • Please try to stay on topic This means you Greg we have a chat thread already
Ask away!


We'll also keep a list of frequently answered questions.

Q: Why aren't there any FAQ yet?

^ Please rephrase that in the form of a question.



But seriosly folks, it is my opinion that you will probably get more mileage
out of your question if you state it intelligently and be sustinct. Also, do
not be afraid to do a Google search first or maybe post a URL to a thread or
Web site that discusses your topic in question.

But the bottom line is, don't be afraid to ask. Everyone starts somewhere.
You will not be looked down upon for asking in here.

As someone who likes to learn as much as I can about guitar gear, this is a great idea for a thread. (I also just wanted to be on the first page )

I did have a question that I either can't understand via answers on Google, or if I just can't find them:

What is the difference between an optical and a non-optical compressor, in terms of tone?

an optical compressor uses a photo resistor and a light source (like an LED), this produces a particular lag, delay or ramp (in the attack and release). it kinda has it's own type of response.

there are many factors in how non-optical compressors work so it is hard to say how they exactly differ from optical compressors. in fact there are particular non-optical compressors that try to emulate (and do emulate quite successfully) optical compressors.

I think a confirmation on someones answer (as long as its right) is good though.
If I only get an answer from one person, I'm not as likely to follow it unless I get conformation from another knowledgeable person.
YMMV

An analog pedal has transistors that shape the sound. A digital pedal actually has a processor (like in your computer) that shapes the sound. Its really just a bunch of 1s and 0s.

Did I do well?

Thats more or less correct.
Analog can also include IC's (LM358, JRC4558, LN1458, CD4053, etc.).
Just because it has an IC doesn't mean its digital (that argument has come up before).
You can have an analog IC, or a digital IC.

You did just fine.

What does the 'plexi' in Marshall Plexi come from?

The early Super Leads had a plexiglass front panel, as opposed to later metal panels. The name Plexi just kind of stuck.

i think the early super leads (1959) also had plexiglass from '65 til '69

that might have been what you meant though.

I knew about the Plexiglas panel I guess my question
was more of is it a thin layer of Plexiglas glued onto
the front panel of the metal chassis?

If so, why?

I assumed they did that because Plexiglas doesn't
conduct electricity and it helped prevent accidental
electrocution in these early amps.

i believe it was just straight plexiglass (mounted to the front of a metal chassis that houses the circuit).

if you want a more modern example of an amp that uses plexiglass for the front panel, look at Orange amplifiers. i believe just about all their higher end amps uses straight plexiglass front panels, it literally just a piece of plexglass attached to the chassis



see the white panel on the front of the Orange chassis? that is all plexiglass.

so the panel itself is all plexiglass, and yes it is mounted to the front of the metal chassis. i don't know if they actually glued it though. i'd imagine there is enough mounting parts to keep it secured on there.

i think it was just aesthetic

a digital pedal converts the signal from the guitar into a digital/discrete signal represented by logical 1's and 0's. this digital signal is then processed by a DSP (digital signal processor) chip and then reconverted back into an analog signal for output to the amp.

i would say the analog/digital/analog (ADA) conversion is the big defining characteristic of a digital pedal.
