Pesado Tamper & Basket
I recently purchased a Pesado 58.5 basket and tamper from site sponser coffeeparts. I've noticed the tamper, whilst being a fairly snug fit with the basket, still has a slight gap around the edge, therefore not creating the greatest seal on the puck.
I'm seeing a fair bit of channeling coming from the edges when using the naked portafilter.
Any suggestions on how to combat this?
Usually a combination of dose / grind being too high / too fine for the machine / basket / coffee in use. The water is simply taking the path of least resistance.

If your dose is right up near the brew head try dropping 1 - 2g and see what happens. If the flow is improved adjust grind to taste.
Vice versa If your dose is already quite low / grind quite fine.
