  1. Just a sidestep: years ago I was playing a small tour in Switzerland. Salzhaus promised to rent all equipment our band needed. My set was an old 4x10, and that fab Mesa 400+! That is one powerful and well behaving amp. It is still pretty expensive, but the glow of the tubes and sound it produces... I am using a solid state Glockenklang Soul, because it weighs much less.

  2. Smith and Jones talked about Renault 5...

     

    Electrorux delivered me a dishwasher that had electricity connected to the metal cover, and the ON/OFF switch had failed. I reclaimed the company, but they said I have to call a repairman!

    NEVER EVER AGAIN!

     

    Never. Ever.

     

    Never. Ever.

     

    Dyson's vacuums use all their electrical power to make an incredible amount of noise. No suction power at all. I managed to sell the top of the line unit to a colleague. She does not talk to me anymore.

     

    Philips was said earlier, MTV, ikea, and Yahaya turntables (including cartridges) belong to the same trash. All is the same Chinese crab. I also hate this T9 predictive text system (actually: the chastity corrector).

  3. An addition:

    If the effects of your board cost £1000, why do you want to power them up with a £20 PSU?

     

    This is slightly similar than an amp + a cab. If you have invested £1000 to an amp, why are you trying to pair it with a £100 cab? A good cab (or a PSU) is a complex set of knowledge, development, and quality materials - although it doesn't have lots of knobs, or fancy lights.

  4. Some basic rules:

     

    - capacity of the PSU is measured in amps (like 3000 mA, or 3 A)

    * the capacity needs to be more than the consumption of the pedals

    * check the manufacturer's website for specs and add all mA together (chorus + comp + eq +...) to get the total consumption

     

    - separate, isolated outputs lessen ground loop, and noise issues

    * may be or not necessary depending on the complete board

    * analog and digital may not always work together if they are daisy chained

     

    - some daisy chaining may be necessary if the board has many fx

     

    - a dist/OD/fuzz usually consumes just few mA, while a digital reverb, or a delay may need hundreds of mA (and one output)

     

    - a functional PSU does not cost an arm and a leg

    * extras raise the price, special fx may need those functionalities (12 VAC, 18 VDC...)

    * secured cabling is important for a functional board

     

    - it is not uncommon that a PSU creates changing magnetic field around it (because it works with a changing electric field, 50 Hz)

    * the field degrades very quickly, but a wah wah (or any unit that gets interfered) should be situated far from the PSU: every inch counts

     

    - liquids (water, beer, wine...) are not good for any electrical unit

    * a board with high feet may be good against sudden waves

     

    - as with audio cables, keep all cables in pristine condition to prevent shocks!
