Web shops
A list of links to web shops that sell parts for building effects.
Newtone
Dutch web shop focused on the DIY builder. Great selection of parts with decent prices. Pre-payment only, no Paypal, Ideal or credit card. Really fast delivery if items are on stock, generally within 2 to 3 working days. Offers possibility to send small orders by letter which can save you 4 Euros.
Musikding
German webshop focused on the DIY builder. Great selection of parts with good prices. Delivery times are an issue, it can take more than a week before orders are picked and then it can take up to another week before the order gets delivered.
Banzai
German webshop selling all kinds of items and parts related to making music and building instruments, effects and amplifiers. Great selection of parts with good prices. Delivery can be slow, up to 7 working days.
Bitsbox
UK webshop for electronics hobbyists and makers with quite a nice catalogue for effect builders also. Attractive international shipping fees, especially for smaller orders. Relatively fast delivery, within 5 working days.
Silicon Ark
Love this web shop for their great selection of NOS transistors and diodes. They even had (with the emphasis on had) MA165 diodes. Yeah, bought all they had left. What's so special about these diodes? One word: Mostortion. Fast delivery also, orders arrive within 4 to 5 days.
Nucleon FX
Dutch web shop with custom designed PCB's and some components.
Tayda Electronics
Thai web shop renown for their low prices and good selection of parts. Take care with what you order, not all parts are of a trusted origin, especially components like IC's or branded capacitors, these might be fakes. Their Alpha pots seem to be the real deal though and also their powder coated enclosures are nice, especially considering their low price. Delivery is extremely slow though, orders can take up to more than a month to arrive.
Conrad
Big German web presence of which I knew it existed but where I stumbled upon by accident when I needed C25K pots and 2N7000 transistors for a Mosfet based fuzz. Also ordered some of their 0.25mm² wire which looks exactly the same as the 0.25mm² wire from Musikding. Fast delivery, within 2-3 working days.
eBay
eBay can be handy for getting stuff in bulk like capacitors or resistors. Delivery times vary wildly as most merchants of electronic components are Chinese so you're left to to whims of the customs of the importing country. Expect 2 to 4 weeks for delivery. Also be aware of components with prices that are too good to be true, those might be fakes.
AliExpress
Great for things like knobs, DC sockets, switches and other components that regular web shops get from China too. In some cases ordering directly can be cheaper.
Daier
For switches and knobs, check Daier.
GD-PARTS
More knobs. And also ludicrously expensive vacuum tubes.
Kokko
Nice cheap effects for modding.
Martoparts
Dutch web shop with good prices and the possibility to send small orders by letter.
Budgetronics
Good prices, low shipping costs. And they stock CA3260's. Something to do with Mostortions.
RS Components
Great for things like good quality capacitors and resistors. You need a Chamber of Commerce registration though.
TME
Polish web store, can sometimes be a cheaper alternative.
