Soldering shouldn't be a problem, I fixed cables in the past. Non soldering sounds a bit risky
I didn't evalutate the possibility of making my own cables... but interesting indeed.
what things should I be aware of when making speaker and patch cables. In fact I don't know the difference and it seems pretty important
Are golden plugs a must ?
If you can solder, you will save yourself alot of money.I make all my own cables.Here's a few things to keep in mind:
INstrument cable for guitar, patching between pedals and rack gear is a 1 conductor cable with an outer shield. The inner conductor carries the signal and the outer shield is used to make a ground connection
Speaker cable is "unshielded" and normally has 2 seperate conductors. Never mix speaker cable for instrument cable
Two very good and affordable cable manufacturers are Mogami and Canare. Both companies make excellent uality cable and are readily available as well as affordable
Some of the more exotic cables like quantum,Klotz Lagrange and evidence are all excellent but can be very expensive.So Mogami and Canare are usually going to give you way above average quality while being reasonably priced.
For instrument cables, I like to use Mogami 2524 and sometimes Canare GS-6. The Canare GS-6 has a braided shield which needs to be unraveled at the ends before you can solder it to a plug. On the other hand, this braided shield makes the cable very strong and reliable.
The Mogami 2524 has a little more detail than the Canare so I prefer it but both are very good cables and easily give sound quality that is as good as anything planet waves or Monster Cable sell.
For Speaker Cables, Mogami makes :
3103- 2 Conductor speaker cable approx $2.00 per foot
3104- 4 conductor (quad) style cable approx $3.60 per foot
4S6 , 4S8 , 4S11 all of which are quad style speaker cables.
For audio connectors you can use switchcraft SW 280 plugs which are 1/4" straight and SW 226 which are right angle
Neutrik conectors are also very good but are usually considered overkill for going betweenamps and effects. If you have enough room to fit these larger connections they are fine, but most neutrik 1/4 plugs are very big and can be hard to fit in a narrow space.
