Need clarification on terminology...

Hey guy. I've been playing for almost 4 years so I'm ashamed to ask this. But I have no clue what a cabinet, pre-amp, stack are.

Can someone fill me in, and what each is used for?

well, a cabinet is short for speaker cabinet. it is a box constructed to hold speakers alone. They are used with heads *amplifiers not connected to speakers* or as an extention for a combo amp, which holds speakers AND the amp its self. The pre-amp us a series of tubes that shape and color your tone before it goes to the power section of your amplifier. The powersection also consists of tubes but are much different and do a much different job. A Stack is a combonation of a head and speaker cab. They are stacked ontop of eachother, which is why they are called stacks.

Hope that helped. its Kind of hard to explane not knowing exactly how much knowledge of amplifiers and such you have before hand, but if there is anything else I can help with just let me know.

A combo is a single unit containing both the pre-amp (distortion, gain, EQ, etc.) controls and speakers.

Not all preamps contain tubes, however. Solid-state (SS) amps do essentially the same things digitally (someone can probably help me out here--I'm not sure "digitally" is correct, but I don't know the proper terminology). Companies have worked long and hard to get SS to sound like tubes (like TVs used to have), but it ain't the same (I'm sure someone will take exception to that). The advantage to SS is that you never have to replace the tubes, which can be costly depending on how many you have.

The advantage to having separate head (head contains preamp) and cabinet is power and versatility.

=my two cents

Most SS amps are analog, transistors not computer chips.

Funny, at 3:00 a.m. I couldn't think of analog or transisters--all I could think of was digital. I knew that wasn't right. Thanks.
