I should firstly state in this review that the reason I happened upon this item was because I had previously bought a Clearsonic amp shield for my 2x12 cab. Being a guitarist who chooses from multiple cabs according to the venue, it was always going to be interesting to see if the smaller shield would lead on to further Clearsonic purchases for my other cabinets.
The smaller amp shield proved to be a revelation for me and, due to it becoming so indispensable so quickly, I decided something similar for my 4x12 cab was not a luxury purchase - it was a necessity!
Within a month I was back on the Thomann's website where I found this wonderful little problem solver! With this "H" extender and some 6mm perspex procured locally, I am now able to build up the smaller amp baffle to the height required for my 4x12. Wow :)
The Clearsonic products are pretty new to guitarists in general but I have made multiple purchases in a short period and on each occasion, I am happy to say it has been money very well spent.
