Hello -
I'm new here. I came across this site after upgrading my 12 year old from a classic to acoustic amplified guitar. After music his next favorite hobby is electronics, so I suggested that we build an amplifier, at least at first.
I found a pretty straightforward circuit called the Ruby amp:
**broken link removed**
I have a number of questions and I know there are some electronics wizzes who visit this site and are kind enough to share their knowledge with neophytes like myself.
One question I have is, after insisting that gain is the electronics term for volume, sure enough the above circuit has both a gain and volume control. Can someone explain the difference?
I'm unfamiliar with some of the values shown on the schematic. For instance, there are capacitors marked 47n. I am familiar with pf, and µf. What's n? Also, there are resistors with a numeric suffix, such as 1M5 and 3k9. What do the 9 and the 5 stand for?
Could a computer speaker be used to amplify a guitar?
Can this amp be boosted to deliver more volume?
Are there other more powerful circuits out there?
What additional effects can we add?
Any info will be greatly appreciated!
